摘要： Systems and methods of generating and using auxiliary information (38) for reconstructing digital images (34) that have processed through print-scan channels (18) are described. Auxiliary information (38), including values of reference pixels, is extracted from an input image (34). Output image data (36) containing a representation of the input image (34) is generated. The auxiliary information (38) is stored in association with the output image data (36). The auxiliary data structure (40) is decoded to produce decoded auxiliary information (48). Scanned image data (44) that is obtained from a hard copy (42) of the output image data (36) is registered and color-corrected based on the decoded auxiliary information (48) to obtain an output image (46) corresponding to a high-quality reconstruction of the input image (34). The auxiliary information (48) may include coded transform coefficient data from which the input image (34) may be reconstructed using the registered and color-corrected output image (46) as side information.

Descriptive features of at least one of the affinity- grouped segments are computed. At least one of the affinity-grouped segments is classified as a main body segment based on the computed descriptive features. Additional affinity-grouped segments are classified as to a document function based on the computed descriptive features. Classified affinity-grouped segments are assembled according to their classified document functions to provide the main content.

摘要： Methods, apparatus, and machine-readable media for segmenting and enhancing images are described. In one aspect, gradient magnitude values at respective pixels of a given image (16) are determined. The gradient magnitude values are thresholded with a global threshold to produce thresholded gradient magnitude values (20). The pixels are segmented into respective groups in accordance with a watershed transform of the thresholded magnitude values (20). A classification record (18) is generated. The classification record (18) labels as background pixels ones of the pixels segmented into one of the groups determined to be largest in size and labels as non-background pixels ones of the pixels segmented into any of the groups except the largest group.

摘要： A method and system for extracting Web content is disclosed. In one embodiment, Web content in a Webpage is extracted by identifying paragraphs in the Web content based on line-break node determination. A range of text-body associated with the identified paragraphs is then identified using a maximum scoring subsequence. Further, the identified text-body is refined using a heuristic rule of substantially horizontal alignment. Furthermore, one or more titles and one or more images associated with the Web content are extracted. Moreover, the Web content including the identified paragraphs, the one or more titles and the one or more images are outputted.
