Abstract: Accurate edge detection requires eliminating pixels that have erroneously been classified as edges prior to image processing. Present systems and methods group recorded background-to-medium and medium-to-background transition points in sets and fit a regression line to each set. Error values are then calculated for the fitted lines, sets with error values that exceed a predetermined amount are excluded and the document edge is identified using the remaining lines. Accordingly, erroneously classified pixels are eliminated quickly enough to keep up with the scanning rate and the edges of a scanned document image can be detected in real-time.

Abstract: Detecting skew and determining skew angle using the front of a document by determining background-to-document transitions. Incoming scanlines are interval sampled in the fast scan direction every nth pixel. The samples are collected and organized into a two dimension array comprised of scanline based rows and interval based columns. The collected and organized samples are analyzed by intervals to determine a scanline (row) where a specified sampling condition exceeds predetermined threshold. The corresponding row-interval point forms a background-to-medium transition point of the edge of a document. When two or more background-to-medium transition points are found from different intervals the skew angle can be determined using linear regression.

Abstract: Some embodiments are directed to a method of automatically modifying a scanned image of a page from an input document comprising a plurality of pages. First, scanned images of the plurality of pages are obtained. Next, a user selection for an output orientation of an output document and optionally value of N for an N-Up operation is received. Thereafter, input orientation of each scanned image is detected. Then, the scanned image is rotated, based on the detected input orientation, the output orientation and the value of ‘N’ if provided by the user. Next, the rotated scanned image content is resized so that it fits on a page. Finally, the output document is prepared that includes pages in the output orientation.

Abstract: Disclosed is a processor-implemented method for processing image data of a document using an apparatus. The processor determines pixel classifications and counts for each classification, classifies the image, selects a billing tier for which to bill the image, determines counts of pixels for marking to output the image (e.g., in device dependent space), and then can adjust from the selected billing tier to a different billing tier based on the image classification (e.g., and/or using determined counts of pixels for each classification and determined counts of pixels for marking). Counts of pixels can be adjusted using an offset, or calculated using a combination of the determined counts (e.g., combining counts from both independent and dependent spaces). By adjusting the tier at which to bill data, more accurate billing can be implemented for documents with contone or grayscale image data, for example, with greater customer satisfaction.
