    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.

    摘要: Systems and methods according to the present invention provide techniques to automatically crop an image to a desired size. Automating the cropping process, while at the same time providing a high quality, cropped image, can be accomplished by employing a comprehensive approach that includes one or more of contextual cropping (e.g., basing cropping decisions on elements within the image to be cropped itself), training the cropping mechanism (e.g., using previously cropped versions of the same image or related images) and multiple operational modes (e.g., selecting one of a plurality of different cropping techniques for cropping a particular image).

    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.
