TL;DR: The results show a slight influence of image format and compression levels in flat or slightly flat surfaces; in the case of a complex 3D model, instead, the choice of a format became important and processing times were found to also play a key role, especially in point cloud generation.
Abstract: The aim of this study is to evaluate the degradation of the accuracy and quality of the images in relation to the TIFF format and the different compression level of the JPEG format compared to the raw images acquired by UAV platform. Experiments were carried out using DJI Mavic 2 Pro and Hasselblad L1D-20c camera on three test sites. Post-processing of images was performed using software based on structure from motion and multi-view stereo approaches. The results show a slight influence of image format and compression levels in flat or slightly flat surfaces; in the case of a complex 3D model, instead, the choice of a format became important. Across all tests, processing times were found to also play a key role, especially in point cloud generation. The qualitative and quantitative analysis, carried out on the different orthophotos, allowed to highlight a modest impact in the use of the TIFF format and a strong influence as the JPEG compression level increases.

TL;DR: In an electronic camera, an image file can be erased, and when the image file is erased, a state of notification to the user is changed in accordance with the data attached to an image.
Abstract: In an electronic camera, an image file can be erased, and when the image file is erased, a state of notification to the user is changed in accordance with the data attached to an image. In the electronic camera, the data attached to the image indicates whether or not the image file previously has been transferred from a storing area where the image is stored at present to another storing area.

19 Oct 2004TL;DR: In this article, a correction parameter is determined for an image file stored in an apparatus and added to the file in advance before printing, and the image is corrected on the basis of the correction parameter in printing, thereby shortening the processing time.
Abstract: Conventionally, when a correction parameter is determined on the basis of the feature of an image obtained by analyzing image data, and the image is corrected, the processing speed becomes considerably low. In this invention, for an image file stored in an apparatus, reduced image data held in the file is analyzed to determine a correction parameter in printing, and the image is corrected on the basis of the correction parameter, thereby shortening the processing time. When an appropriate correction parameter is determined for an image file stored in the apparatus and added to the file in advance before printing, and the image is corrected on the basis of the correction parameter in printing, the processing time is further shortened.

TL;DR: In this paper, an image extractor for obtaining original image data from an original image file included in an original Web page, and an image file generator for generating a new image file into which the original data, display control parameters of the original image, advertisement image data of an advertisement image, and display control parameter of the advertisement image are integrated.
Abstract: Provides a proxy server for loading advertisements in a Web page. An example embodiment includes: an image extractor for obtaining original image data from an original image file included in an original Web page; an image file generator for generating a new image file into which the original image data, display control parameters of the original image data, advertisement image data of an advertisement image, and display control parameters of the advertisement image are integrated, wherein the display control parameters of the original image and the display control parameters of every advertisement image are used to define how long the original image and corresponding advertisement image are displayed; and a Web page modifying device for replacing said original image file with said new image file in said Web page. A method of displaying a Web page, loading advertisements in a Web page, and an apparatus therefore are also provided.
