Image display and archiving system and method

Abstract: A system 10 and methods for acquiring and archiving images derived from multiple sources with minimal operator interaction and understanding of the archiving computer 11. The system 10 and methods provide for reception of digitized images via modem 24 from a remote source, and the input of images from local sources including a digital photographic image source 25 such as a digital camera or 35 millimeter digitizing camera data back, an optical scanner 23, and digitized images previously stored on magneto-optical disk or digital audio tape. The system 10 also archives and distributes image and document data to multiple destinations, including a magneto-optical drive 22, digital or hard disk drive 15, and to laser or photographic quality continuous tone printers 26, 27. One key aspect of the system 10 and methods is that the operator is not given access to the operating system of the computer 11 and can only perform a predetermined set of functions that correspond to graphical icons 30 disposed on the computer desktop 17 (monitor 12). Each of the icons 30 launches a set of linked macro functions that initialize the modem 24, control data transfer, format the received image data into a predetermined format, attach textual data to the image files, and automatically archive or print the files. Submenus are provided during operation that permit certain selected actions related to the macro that is being run.

Lossless data embedding for all image formats

Abstract: Lossless data embedding has the property that the distortion due to embedding can be completely removed from the watermarked image without accessing any side channel. This can be a very important property whenever serious concerns over the image quality and artifacts visibility arise, such as for medical images, due to legal reasons, for military images or images used as evidence in court that may be viewed after enhancement and zooming. We formulate two general methodologies for lossless embedding that can be applied to images as well as any other digital objects, including video, audio, and other structures with redundancy. We use the general principles as guidelines for designing efficient, simple, and high-capacity lossless embedding methods for three most common image format paradigms - raw, uncompressed formats (BMP), lossy or transform formats (JPEG), and palette formats (GIF, PNG). We close the paper with examples of how the concept of lossless data embedding can be used as a powerful tool to achieve a variety of non-trivial tasks, including elegant lossless authentication using fragile watermarks. Note on terminology: some authors coined the terms erasable, removable, reversible, invertible, and distortion-free for the same concept.

Hierarchical data storage management

Abstract: A system and method for managing the storage of files within an HSM system incorporate an architecture and methodology that facilitate the storage and retrieval of large image files as part of an overall image processing workflow. In particular, the system and method may find ready application in a workflow that involves the processing of groups of images associated with particular customers, projects, or transactions, and may act as a storage server for a client application that implements the workflow. The system and method may be useful, for example, in handling the storage of images uploaded from scanned photographic film, or digital images submitted to a photo-processing shop by amateur or professional photographers. In this case, the client application can be a photo-processing application that could provide for various media formats, sizes, and quantities of image reproductions for a consumer. As another example, the system and method may be useful in handling the storage of medical diagnostic images associated with a particular medical patient or study. In this case, the client application could be a picture archival communication system (PACS) that manages the archival of imagery for viewing by physicians. Further, the system and method may be useful in handling the storage of images associated with particular printing jobs, e.g., for publishers, advertising customers, and the like. In this case, the client application could be a digital prepress workflow application.

A method and system for accelerating a user interface of an image capture unit during play mode

Abstract: A method and system for accelerating a user interface on a display of an image capture unit is disclosed. The first aspect of the invention comprises a method and system for providing a low resolution image (606), medium resolution image (608) and high resolution image (604) within each image file (346) and allowing the medium resolution image to be viewed on the display. The second aspect of the invention comprises a method for providing a low resolution image within each file that is associated with a high resolution image within each image file, allowing the low resolution image to be viewed on the display and causing the related high resolution image to be displayed on top of the low resolution image dependent upon the quality of the low resolution image. The method and system also includes allowing for navigation between low resolution images based upon user interaction.

Method for monitoring internet dissemination of image, video and/or audio files

Abstract: An automated monitoring service downloads image files (including, e.g., graphic and video files) and audio files from various Internet sites, and checks these files for the presence of embedded digital watermark data. When found, such data is decoded and used to identify the proprietor of each watermarked file. The proprietors are alerted to the results of the monitoring operation, often apprising such proprietors of unknown distribution of their image/video/audio properties.
