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.

摘要： Systems and methods according to the present invention provide techniques to reliably detect edges, lines and quadrilaterals, especially those with low local contrast, in color images. Edges can be detected using a color gradient operator is based on color distance with a non-linear weight determined by the consistency of local gradient orientations, thereby significantly improving the signal/noise ratio. In detecting lines, a variant of the Gradient Weighted Hough Transform can be used employing both the edge strength and orientation. Multiple non-overlapping quadrilaterals can be detected using a process which includes quality metrics (for both individual quadrilaterals and for a set of non-overlapping quadrilaterals) and a graph-searching method.

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