TL;DR: By aligning with the dominant format in neuroimaging, NIfTI-MRS enables the use of mature tools present in the imaging community, demonstrated in this work by using a dedicated imaging tool, FSLeyes, for visualization.
Abstract: Multiple data formats in the MRS community currently hinder data sharing and integration. NIfTI‐MRS is proposed as a standard spectroscopy data format, implemented as an extension to the Neuroimaging informatics technology initiative (NIfTI) format. This standardized format can facilitate data sharing and algorithm development as well as ease integration of MRS analysis alongside other imaging modalities.

TL;DR: The JPEG Snack (ISO/IEC 19566-8) as discussed by the authors is an international standard developed by the Joint Photographic Experts Group (JPEG) to enable image-rich content creation and sharing.
Abstract: Most people watch short-form content, especially when viewing it on their smartphones. While short-form content is widely used for entertainment, it is also for essential information sharing with broad audiences. The importance of short-form content is self-evident, as Facebook and YouTube have introduced Facebook Reels and YouTube Shorts, respectively. The rapid, widespread adoption of short-form content indicates the need for a new international standard to ensure the interoperability of broad content and content creation tools. This article overviews a new international standard development effort in the Joint Photographic Experts Group (JPEG) in ISO/IEC JTC1/WG1 to create JPEG Snack (ISO/IEC 19566-8) to enable image-rich content creation and sharing. JPEG Snack images, audio, videos, and captions are embedded in the standard JPEG-1 (ISO/IEC 10918-1) image file. The JPEG Snack file comprises two components: i) a default JPEG-1 image and ii) an ISO base media file format (ISOMBFF (ISO/IEC 14496-12)) box-based file extension. The JPEG-1 image portion makes the file compatible with existing JPEG viewers for preview and user navigation, while enhanced JPEG Snack viewers can display the rich image/audio/video/caption short-form content. The article presents essential features of the JPEG Snack and its comparison with JPEG-linked media format (JLINK (ISO/IEC 19566-7)) and JPEG 360 (ISO/IEC 19566-6). It also presents the pros and cons of JPEG Snack over high-efficiency image file format (HEIF (ISO/IEC 23008-12)).

TL;DR: In this paper , the authors classify images into raster and vector files on the basis of their resolution and the quantum of detail they contain, and provide practical information on where, when, and how to use a JPEG, HEIF, BMP, TIFF, GIF, PNG, RAW, or DICOM file.
Abstract: Expensive digital or phone cameras do not guarantee a perfect picture and a good presenter must learn to use these to produce high-quality pictures for medical presentations. Image files are classified as raster and vector files on the basis of their resolution and the quantum of detail they contain. Raster images are dependent on resolution because each pixel is contributing to the whole; more pixels mean higher resolution and higher quality of the image. Conversely, fewer pixels mean when enlarged the image will breakup or pixilate. Repeated editing of raster images lowers their quality. A vector image is a flexible and scalable digital graphic based on mathematically calculated paths and are unaffected by resolutions and maintain image quality even after multiple handling. Two types of digital colour system are discussed. Since all the presentations are in digital format, every picture projected is an image file. There are a variety of formats, and each has special qualities and shortcomings. One needs to choose horses for courses. Useful practical information on where, when, and how to use a JPEG, HEIF, BMP, TIFF, GIF, PNG, RAW, or DICOM file is provided.

TL;DR: In this paper , the authors developed a method to merge two types of images which is grayscale and RGB image with the help of MATLAB, which results in the generation of three digital output files which are Output_red, Output_green and Output_blue.
Abstract: Multimedia apps on the Internet have grown in popularity in recent years. Because of the rapid development in the usage of multimedia information, data storage and transmission security has become increasingly crucial. Encryption is a useful tool for keeping multimedia data private. Various approaches for encrypting photos to make them more secure are discovered on a regular basis. Here developed a method to merge two types of images which is grayscale and RGB image. Initially, the image is converted into a digital format with the help of MATLAB. It is then fed to the top image module for merging and a digital output file is generated. This file is then reverted back to analog form for visualization purposes with the help of MATLAB. For computing RGB image, the image is split into 3 classes containing the reds, greens and blues of the image. These classes are separately convolved using the image multiplier module designed in Xilinx ISE. This results in the generation of 3 digital output files which are Output_red, Output_green and Output_blue. These files are then combined to form a single-color image and visualized using MATLAB. The structure is shown below. For a grayscale image, a single image multiplier is sufficient to compute or perform image merging. Here, it's no need to split the image into RGB because the image consists different shades of black. Upon processing, a single digital file is generated and this file is visualized using MATLAB.
TL;DR: The results of the Least Significant Bit [LSB] method in this study are successful in inserting a .txt file into the hidden original image so that it does not change the visualization of the image but only changes the image size from 56.9KB to 732KB.
Abstract: Copyright is a direct right granted to the creator of a work in any form that is real and recognized in accordance with the provisions of the legislation in force in the area. Copyright infringement is very detrimental to the creators of works who have tried hard in creating a work. The steganography technique can be a solution to insert hidden messages into digital data. In writing this scientific research journal, an application was made to give a hidden message sign to an image. The goal is to protect copyrighted works from being easily recognized by irresponsible parties. Making this simple application using MATLAB R2021a software. By using the Least Significant Bit [LSB] method, what happens is that the data bits will be inserted into the digital image bit by changing the last bit. The result is that the image inserted with the message does not experience significant changes, but when the image undergoes an extraction process, the inserted message will appear. The results of the Least Significant Bit [LSB] method in this study are successful in inserting a .txt file into the hidden original image so that it does not change the visualization of the image but only changes the image size from 56.9KB to 732KB

TL;DR: In this article , the authors compared the reliability of the CORA angle between the two image formats; Dicom and Jpeg using new software (OsteoAid) to ensure that the new software is reliable for both image formats for the correction.
Abstract: This paper aims to test the reliability of digital osteotomy's correction angle between the two-image formats; Dicom and Jpeg using new software (OsteoAid). This is to ensure that the new software is reliable for both image formats for the correction. The hypothesis is to compare the reliability of the Centre of Rotation of Angulation (CORA) angle for each intra-rater and inter-rater reliability. CORA was defined and the angles of all patients’ legs were checked for correction to determine the accuracy of both image formats using an intra-class correlation coefficient (ICC). Thirteen digital long leg radiographs with longstanding positions from the frontal axis showing patients with both tibia deformities were examined. Those images were accessed from the Picture Archiving and Communication System (PACS). Three medical officers (raters) who were involved in an osteotomy used the same medical image format twice at a two-week interval. Using the Dicom format, the mean correction angle score of each rater is at excellent level: 0.949 (Intra-rater1), 0.987 (Intra-rater2) and 0.968 (Intra-rater3). Scores of each rater for Jpeg format are also excellent: 0.904, 0.928 and 0.962 respectively. The inter-rater reliabilities of the correction angle were 0.979 and 0.972 (p<0.001) respectively for each format. The principal finding of this study was that OsteoAid showed excellent reliabilities and consistency in preoperative planning in finding CORA and correction angle using both image formats. This indicates that the two image formats are comparable in obtaining CORA angles.
TL;DR: The algorithm used is the Swiss army knife data compression, using this method, the compression results from the value of k have different compression results for each value, and the compression Results will be beneficial in sending and moving image files more easily.
Abstract: As technology develops, the process of sending files no longer needs to be done manually. Data or files can be sent electronically via email. The image file size is sometimes very large, where the better the quality of the resulting image, the bigger the pixel size needed to record the image. With a very large image file size, the transfer process may fail, because the media storage space exceeds its limit. The solution to this problem is how the image file can be compressed in order to speed up the transfer and storage of image files. Image compression is done by reducing the size of the image file by reducing the bits in the image file, but not eliminating the information data in it. By compressing, large data will be reduced in size so as to save storage space. In this study, the algorithm used is the Swiss army knife data compression, using this method, the compression results from the value of k have different compression results for each value, and the compression results will be beneficial in sending and moving image files more easily
TL;DR: In this paper , the differences between Lightroom and Photoshop are identified and compared to identify the areas in which each program is distinguished and to make the most of each program to achieve maximum effectiveness in terms of editing digital raw photo files.
Abstract: : Digital photography is developing in a great way, in which manufacturers of digital raw photo file processing software are seeking to continuously update the software and provide it with capabilities that provide the photographer with the speed of working on digital raw photo file processing while achieving the maximum possible quality of output, which leads to an increase in the effectiveness of digital raw photo file processing. Adobe, since its founding in December 1982 by Charles Geschke and John Warnock, is considered a leading manufacturer of software for editing digital photos and videos, special effects, and animation. The company has provided two programs, Adobe Lightroom and Adobe Photoshop can both edit raw photo files of different types, which made the professional photographer confused, making him resort to editing raw digital images in either of the two programs according to his personal preference Thinking that they are similar in accomplishing that task, so this research attempts to shed light on the differences between them and to identify the areas in which each program is distinguished and to make the most of each of them achieve maximum effectiveness in terms of editing digital raw photo files, coinciding with the issuance of the latest update for both programs The Adobe Lightroom program is equipped with many new features that make the user able to perform more complex processing to the digital raw photo files, without resorting to another program without compromising the quality of the raw digital image file.

TL;DR: In this paper , the intelligent information protection model was proposed to enhance the security from the harmful internet activities in big data storage systems, and the program implements all the main functions that one can only expect from such a solution: copying disk partitions, removable media and password protected and compressed files.
Abstract: In general, information can be protected from various harmful Internet activities and various problems associated with computer malfunctions. Although not the most convenient program for creating a copy of a disk, it is quite complete in its capabilities. It allows you to copy and restore both individual partitions and the entire disk, and the disk image can be read and written over the network via a parallel or USB port, and stored on CD-R / RW or other removable media. In this paper, the intelligent information protection model was proposed to enhance the security from the harmful internet activities in big data storage systems. This program implements all the main functions that one can only expect from such a solution: from one hard disk to another hard disk or to a file (disk image), copying disk partitions HDD, removable media and password protected and compressed files. The package contains a lot. It allows you to view a disk image and recover individual files. The program provides functions to check the disk surface for errors and bad sectors and has the ability to copy “from sector to sector” if the user wants to get an exact copy of the disk. A very simple and intuitive interface makes it easy to back up your hard drive and the process of restoring it later. In the Ghost Explorer window, you can drag and drop files and folders into or out of an image file. Launched from the command line, it has a unique set of features that experienced users know how to handle.
TL;DR: In this article , a compression algorithm such as elias omega code is used to reduce the size of large image files by using a lossless compression type, where the compression results can be returned as before without any bit loss.
Abstract: The habit of collecting data makes the capacity of large storage space smaller, making it difficult for computer users to store large amounts of data or large data. One of the files that are large and usually collected by humans is image files, this takes up a lot of storage space. One solution to overcome this problem is to use a compression algorithm such as elias omega code so that the size of large image files becomes smaller. Elias Omega Code Algorithm is a compression algorithm with a lossless compression type, where the compression results can be returned as before without any bit loss. The purpose of using the elias omega algorithm is so that the image file that is saved becomes a small image file. The results obtained from building an image file compression application are that the image file size becomes smaller, with a compression ratio of 66.5%.

TL;DR: In this paper , a geometric method is proposed to get the position of an image in the PDF document and extracted all the images in that document, which are saved in JPG or PNG or GIF or BMP format as a separate file.
Abstract: PDF is a format of the file that is used for showing research articles mostly. PDFs are actually easy to create, but extracting the data from PDF files is a challenging task. Images contain important as well as useful information which cannot be represented by text. The difficult concepts are better explained by an image than the text. In this paper, a feasible way to extract images from the PDF file is explored. This work is attempted to extract images from scholarly research publications of PDF files. The structure of a PDF file is entirely different from other file formats. A geometric method is proposed to get the position of an image in the PDF document and extracted all the images in that document. These images are saved in JPG or PNG or GIF or BMP format as a separate file. The resolution and size of extracted image are the same as the original image and are suitable for printing.
TL;DR: In this article , a new methodology for the digital image forgery detection was proposed by combining the analysis of metadata's exchangeable image file format (Exif) information, statistical features and also with the help of error level analysis method (ELA).
Abstract: Fingerprinting of digital images is the process of finding evidence from the tampered images by the use of image’s metadata and machine learning algorithm. In the recent decades, digital images growing tremendously in the people’s life, and digital images have been used in many application areas. Hereafter, digital image integrity should not be taken for granted because now a days popular powerful software used for image editing are available in the Internet at low cost. Because of the technological evolution and the availability of powerful image editing software, digital crimes also increase tremendously. To identify the legitimacy of the image files, we propose a new methodology for the digital image forgery detection by combining the analysis of metadata’s exchangeable image file format (Exif) information, statistical features and also with the help of error level analysis method (ELA) that can help the forensic investigators to authenticate the digital image files by distinguishing the difference between the real image and the fake image.

TL;DR: In this article , a smart format improved object tracking approach is proposed to improve the quality of the captured image files by discarding unnecessary pixels, which is effective in improving the compression ratio of items.
Abstract: In general, selecting an image format is crucial for deciding what kind of results to display in picture searches. Among the most significant discoveries about RAW and JPEG formats, this is. Even yet, most experts in the field are able to tell the difference between the two. Images in JPEG format are widely used because of their quality and convenience. Images are often saved in JPG format before being printed or uploaded online. There are now worries regarding JPEGs' visual quality. This is the most used picture compression format, thus it's required by the great majority of digital cameras. However, this alters the photos irreversibly, rendering them unrecognisable. Selecting an appropriate picture format is the primary challenge here. This research proposed a smart format improved object tracking approach to boost digital image quality. By default, the camera is set to reduce the size of the captured image files by discarding unnecessary pixels. Depending on your preferences, the compression might be higher or lower. Cameras will reject the bare minimum of data if the file size is set too high. As the number of potential viewers increases, the resolution drops. The suggested method is effective in improving the compression ratio of items.
TL;DR: A method that enables compact storage of scrambled data alongside the corresponding (unscrambled) standard CD-ROM disc image is introduced and produces a compact representation of the scrambled data that is derived from the standard disc image.
Abstract: When archiving and preserving CD-ROM discs, data sectors are often read in a so-called “scrambled mode” before being unscrambled and further processed into a standard disc image. Processing of scrambled data into a standard disc image is potentially lossy, but standard disc images exhibit greater software compatibility and usability compared to scrambled data. Consequently, for preservation purposes, it is often advantageous to store both the scrambled data and the corresponding standard disc image, resulting in high storage demands. Here, a method that enables compact storage of scrambled data alongside the corresponding (unscrambled) standard CD-ROM disc image is introduced. The method produces a compact representation of the scrambled data that is derived from the standard disc image. The method allows for storage of the standard unscrambled disc image in unmodified form, easy reconstruction of the scrambled data, and a substantial space savings compared standard data compression techniques.
TL;DR: PatchIT as discussed by the authors is an integrated framework suitable for the systematic and automatized extraction of patches from images based on user-defined geometrical and spatial criteria; patches can be extracted in both a sliding and random manner and can be exported either as images, MATLAB .mat files, or raw text files.
Abstract: Patch-based approaches in image processing are often preferable to working with the entire image. They provide an alternative representation of the image as a set of partial local sub-images (patches) which is a vital preprocessing step in many image processing applications. In this paper, a new software tool called patchIT is presented, providing an integrated framework suitable for the systematic and automatized extraction of patches from images based on user-defined geometrical and spatial criteria. Patches can be extracted in both a sliding and random manner and can be exported either as images, MATLAB .mat files, or raw text files. The proposed tool offers further functionality, including masking operations that act as spatial filters, identifying candidate patch areas, as well as geometric transformations by applying patch value indexing. It also efficiently handles issues that arise in large-scale patch processing scenarios in terms of memory and time requirements. In addition, a use case in cartographic research is presented that utilizes patchIT for map evaluation purposes based on a visual heterogeneity indicator. The tool supports all common image file formats and efficiently processes bitonal, grayscale, color, and multispectral images. PatchIT is freely available to the scientific community under the third version of GNU General Public License (GPL v3) on the GitHub platform.
TL;DR: In this paper , a sub-regional compression (SRC) method is proposed, and its optimal compression quality of the background regions is selected using image quality assessments such as SSIM, BRISQUE, NIQE, and PIQE.
Abstract: As a major Internet of Things information carrier within the greenhouse, image quality and image file size need to be balanced. To reduce image file size while maintaining image quality, a sub-regional compression (SRC) method is proposed, and its optimal compression quality of the background regions is selected using image quality assessments such as SSIM, BRISQUE, NIQE, and PIQE. In addition, a convolutional neural network-based NIMA model to measure image quality is also being introduced. In the end, the SRC method is compared with JPEG compression default mode and JPEG compression with quality 30 in NIMA score, compression time, and compression efficiency, proving the effectiveness of the method. Practical applications Certain vegetables and fruits, such as cucumbers, tomatoes, etc., in most cases are processed directly into the hands of consumers, so the loss is directly attributable to their growth, especially pests and diseases. Monitoring for the above situation is a great improvement, but the increase in monitoring accuracy brings video/key frame to becoming larger. Therefore, it is better to reduce the file size as well as to ensure clarity in regions of interest, viewing the files faster and detecting the losses by humans or machines as easily as possible. This paper investigates the overall process and innovatively introduces deep learning into image quality assessment to better simulate human perception of images, and the research results of this paper can be applied to different models of surveillance cameras to achieve the same results.

TL;DR: In this paper , a smart format enhanced object tracking model was proposed to improve the attributes of the digital images, and the proposed model enhances the objects with high compression ratio and provides the better results.
Abstract: In general, choosing a format for images is a very important factor when choosing a particular type of material in image searches. This is seen as one of the important findings about RAW and JPEG. However, the general majority of experts can imagine the difference between these two forms. JPEG is a common format for photos, and it's handy. If you send images over the web or print images, most often the files are saved in JPG format. However, questions about image integrity have piled up on JPEGs. Of course, this format is described as the most common image compression format and is important for most digital cameras. But this is technically a lossy transformation that degrades the original parameters of the images. This is where the main problem lies, which format to take and save the images creates the problem. In this paper, a smart format enhanced object tracking model was proposed to improve the attributes of the digital images. The camera is initially programmed to make the file smaller by discarding a few pixels. The compression will be more or less depending on the settings you choose. If the file size is set too large, the camera will reject the minimum data. If you need to fit as many views as possible, you set a lower resolution. The proposed model enhances the objects with high compression ratio and provides the better results.

TL;DR: A learning algorithm has been proposed for recognizing many visually spliced images and manipulations in the image and an excellent performance improvement has been observed on several benchmarks, despite not using any spliced image data while training.
Abstract: In recent years, improper image manipulation has become a significant issue across many sectors, such as in the education field, politics, entertainment sector, and social media platforms. In various society sectors, images play a crucial role in interpreting the facts and number of fraud incidents. The fraud and fact can be detected by image manipulation, which is gaining more and more attention in today’s world. Detecting such manipulations images is a major challenging problem concerning many fragmented images’ unavailability as training data. A learning algorithm has been proposed for recognizing many visually spliced images and manipulations in the image. The proposed algorithm also utilizes the existing recorded image Exchangeable Image File Format (EXIF) metadata as a supervisory image for training the model to identify the image is self-consistent, i.e., whether the content of the photo has been generated using a single imaging pipeline. The proposed algorithm is implemented to the errand of identifying and localizing the image splices. An excellent performance improvement has been observed on several benchmarks, despite not using any spliced image data while training. This model will stand out as a vital source to detect morphed images in various industries.
