Method and apparatus for processing metadata

Abstract: Methods and apparatuses for processing metadata are described herein. In one embodiment, when a file (e.g., a text, audio, and/or image files) having metadata is received, the metadata and optionally at least a portion of the content of the file are extracted from the file to generate a first set of metadata. An analysis is performed on the extracted metadata and the content to generate a second set of metadata, which may include metadata in addition to the first set of metadata. The second set of metadata may be stored in a database suitable to be searched to identify or locate the file. Other methods and apparatuses are also described.

Detecting Doctored JPEG Images Via DCT Coefficient Analysis

Abstract: The steady improvement in image/video editing techniques has enabled people to synthesize realistic images/videos conveniently. Some legal issues may occur when a doctored image cannot be distinguished from a real one by visual examination. Realizing that it might be impossible to develop a method that is universal for all kinds of images and JPEG is the most frequently used image format, we propose an approach that can detect doctored JPEG images and further locate the doctored parts, by examining the double quantization effect hidden among the DCT coefficients. Up to date, this approach is the only one that can locate the doctored part automatically. And it has several other advantages: the ability to detect images doctored by different kinds of synthesizing methods (such as alpha matting and inpainting, besides simple image cut/paste), the ability to work without fully decompressing the JPEG images, and the fast speed. Experiments show that our method is effective for JPEG images, especially when the compression quality is high.

System and method for permitting a software routine having restricted local access to utilize remote resources to generate locally usable data structure

Abstract: A Java applet program loaded initially from a remote server is configured to receive additional user annotations for data displayed in an already opened applet window located at the user's client system. To increase the usefulness and flexibility of such program, the user is permitted to preserve/capture, during an interactive session, the modified applet window containing any such input or modifications to the applet window data. Because the updated applet window data cannot be written to the user's client system, however, (due to security restrictions), the present invention instead causes such modified window data to be converted to a standard compressed graphics file format (such as GIF for an image file for example), and then uploaded to the remote server. From there the applet can then open another applet window within a browser program pointing to the location of such file on the remote server. At that point, the user can then perform any desired operation on the file (i.e., such as printing or saving to a local file system) since the browser has access to the local system resources.

Scalable video coding (svc) file format

Abstract: The currently existing ISO/AVC file format is modified by providing extensions to store and access video content currently being defined by the SVC standard. Specifically, extensions to the AVC file format are made to provide a new SVC file format that enables the storage and access of scalable video data. The scalable video data is stored as a single track within a media data section of the SVC file format. New extensions are defined for description entries and boxes within a metadata section of the SVC file format. These extensions provide means for extracting sub-streams or layers from the single track of scalable video data stored in the media data section.

Multiple application and multiple monitor user interface image format selection system for medical and other applications

Abstract: A screen sharing function enables a main executable application, which typically uses more than one monitor, to switch to single-monitor usage as necessary to allow a user to directly interact with other applications that the main executable application invokes. A system including multiple display monitors for displaying multiple user interface image windows associated with corresponding multiple executable applications employs an image format determination system. The image format determination system includes an input processor for receiving command data representing a command to initiate execution of a function of a second application and display of an associated second image window in response to user entry of a command via a first image window associated with a first application. An image format selection processor, in response to the received command data, automatically initiates reduction in size of the first image window to fit a screen of the multiple display monitors and to prevent mutual overlap of the reduced size first image window and the second image window. A display processor initiates generation of data representing the reduced size first image window and the second image window, for presentation on the multiple display monitors.

PHY.FI: fast and easy online creation and manipulation of phylogeny color figures.

Abstract: The need to depict a phylogeny, or some other kind of abstract tree, is very frequently experienced by researchers from a broad range of biological and computational disciplines. Thousands of papers and talks include phylogeny figures, and often during everyday work, one would like to quickly get a graphical display of, e.g., the phylogenetic relationship between a set of sequences as calculated by an alignment program such as ClustalW or the phylogenetic package Phylip. A wealth of software tools capable of tree drawing exists; most are comprehensive packages that also perform various types of analysis, and hence they are available only for download and installing. Some online tools exist, too. This paper presents an online tool, PHY·FI, which encompasses all the qualities of existing online programs and adds functionality to hopefully eliminate the need for post-processing the phylogeny figure in some other general-purpose graphics program. PHY·FI is versatile, easy-to-use and fast, and supports comprehensive graphical control, several download image formats, and the possibility of dynamically collapsing groups of nodes into named subtrees (e.g. "Primates"). The user can create a color figure from any phylogeny, or other kind of tree, represented in the widely used parenthesized Newick format. PHY·FI is fast and easy to use, yet still offers full color control, tree manipulation, and several image formats. It does not require any downloading and installing, and thus any internet user regardless of computer skills, and computer platform, can benefit from it. PHY·FI is free for all and is available from this web address: http://cgi-www.daimi.au.dk/cgi-chili/phyfi/go

Image file formats.

Abstract: This tutorial is about image file formats: what are they, what are they used for, what are their differences and how we choose between them. The tutorial assumes a basic understanding of general digital imaging; of which a quick summary of important features is provided below. Pixel: a digital image is represented as a rectangular grid of dots, where each dot has a specific spatial position and is colour defined. Each of these dots is known as pixels, and represents the smallest unit in a digital image. Matrix Size: the dimensions of a digital image; usually specified in terms of its width and height in pixels. For an image with square pixels, the matrix size also works to define the image aspect ratio. Spatial Resolution: a measure of the amount of spatial detail in a digital image. Resolution is stated as a ratio of physical to sampled dimensions, usually in the form of pixels per cm or dots per inch. The stated physical dimensions depend on whether the application is for acquisition or output. Colour Space: colour space or colour specification system is the method used to represent colour. Greyscale or monochrome images usually use a single intensity gradient. Colour images however, often encode colour in multiple channels, combining them to represent an individual colour. Common examples include RedGreen-Blue (RGB) and Cyan-Magenta-Yellow-Black (CMYK). Bit Depth: bit or colour depth may be thought of as colour resolution, i.e., a measure of the amount of colour

Web services for the DDSM and digital mammography research

Abstract: The Digital Database for Screening Mammography (DDSM) is an invaluable resource for digital mammography research. However, there are two particular shortcomings that can pose a significant barrier to many of those who may want to use the resource: 1) the actual mammographic image data is encoded using a non-standard lossless variant of the JPEG image format; 2) although detailed metadata is provided, it is not in a form that permits it to be searched, manipulated or reasoned over by standard tools. This paper describes web services that will allow both humans and computers to query for, and obtain, mammograms from the DDSM in a standard and well-supported image file format. Further, this paper describes how these and other services can be used within grid-based workflows, allowing digital mammography researchers to make use of distributed computing facilities.
