摘要： A method, apparatus, and article of manufacture provides a zero-crossing filtering region process for extracting data and related image elements from an input image. The input image is processed to generate connected component regions that correspond to image elements within the input image. The connected component regions are generated using a zero-crossing filter that attempts to identify pixels having a significant rate of change in value from their respective neighboring pixels. The connected components are then classified as being part of a foreground image or a background image that allows the image elements to be separated from the input image. Once the input image has been separated into multiple images, each separated image may be processed in a different manner depending upon the separate image's characteristics and uses.

摘要： Discriminating between documents scanned in a batch scanning process is achieved based on various analyses of the constituent document pages. The data provided by the various analyses are compared with each other to determine whether successive pages belong to the same document. Scanned documents result in a page sequence that is analyzed to extract one or more feature attributes for each page. The feature attributes are provided to a feature comparison process in order to assess the similarity of successive pages. If a sufficient likelihood of similarity is found, the compared pages are deemed to be from the same document; otherwise, they are deemed to be from different documents, indicating the existence of a document break. Based on the document breaks, separate scan files may be established. In this manner, the present invention represents eliminates the requirement of user intervention.

摘要： A system for retrieving information from a document. The system includes a document model representative of the document having a plurality of data structures representative of components within the document and a thumbnail image registered with the document model. The registration is accomplished by mapping selected coordinates within the thumbnail image to a data structure selected from the plurality of data structures. In this manner, a user can interact with the thumbnail image coordinates to retrieve data from the document as a function of the components mapped to those coordinates. In a further embodiment of the invention, the retrieved information may be streamed to a word-at-a-time display. This is particularly useful when used in connection with the display of low-resolution images on hand-held devices.
