摘要： A method and system detects and highlights changes in documents and displays those documents in a side-by-side aligned view. Aspects of a source document and a revised document are detected and compared. Similarities and/or differences between the source document and the revised document are identified and visual identifiers are introduced to maintain consistent and accurate alignment between content in the source document and content in the revised document. A merged single file is output containing the aligned side-by-side view of the source document and the revised document, with all differences between the source document and the revised document visually identified.

摘要： An image management method and system provides for storing, indexing, searching, and/or retrieving image data. Keypoints are identified in images, including keypoints in a query image of a query document, and keypoints in potential target document images of a collection of potential target documents. Fingerprint information from the keypoints are generated, and the fingerprint information of a query image is compared with fingerprint information of potential target document images, found in the collection of potential target documents. A best match is determined between the fingerprint information of the query image and the potential target document images. At least one target document image is retrieved based on the determined best match. The retrieved at least one target image may then be displayed, printed or transmitted.

摘要： The image data is analyzed to identify blobs having similar characteristics. Various blobs are gathered together and placed into a foreground plane based on one or more color characteristics and/or spatial characteristics. Each blob gathered onto a foreground plane has a color that is similar to a color associated with that foreground plane. One or more portions of the image data that is not mapped into any foreground plane may be mapped into a background plane.

摘要： A highly efficient method and system for eliminating halftone screens from scanned documents while preserving the quality and sharpness of text and line-art is disclosed. The method and system utilizes a single channel screen frequency estimator module, which generates a screen frequency estimate for image data. The module generates a signal based on the highly filtered image signal at low contrast levels, and based on a reliable estimate to the halftone frequency at higher contrast levels. The single channel screen estimate module has adequate performance in resolution ranges from 300 to 600 dpi.

摘要： A method and a system for separating an image signal into a set of image planes in accordance with a control signal. The system comprises a selector module, an edge processing module and a foreground/background separation module. The selector module receives the control signal and produces a selector signal. The edge processing module receives the selector signal and produces a decision signal. The foreground/background separation module receives the image signal and the decision signal, and outputs a foreground signal and a background signal, a representation of the current pixel of the image signal being included in at least one of the foreground signal and the background.

摘要： A Statistics Module (STS) is disclosed for collecting essential statistics about an image content for the purpose of applying various image enhancement operations such as page background removal and automatic neutral detection to determine if the page is gray or colored. The Statistics Module uses the blurred signal BLR from a De-Screen Module in order to eliminate some of the scanner noise. The output is a special 3D color histogram array.
