摘要： Method and system embodiments of the present invention are directed to automated identification of regions within digitally-encoded images that correspond to objects and features of scenes captured in the digitally-encoded images, a process referred to as ‘perceptual segmentation’ of an image. Regions or segments within an image are first identified by any of various region-identifying or segmentation methods. For each region or segment, features of pixels within the region or segment are employed to compute one or more segment features. The segment features are used, in turn, to identify the region or segment as belonging to a particular type of region or segment, and the region is then accordingly labeled or tagged as a region or segment of the determined type.

摘要： A malfunction diagnosis system of a printer is provided. A printer controller receives malfunction-related input by the user from an input device, which user input specifies a print defect perceptible to the user. It generates image data representing a test print job in response to the user input specifying the perceptible print defect, and forwards the test print job image data to the printing unit to produce a corresponding test printout. Measurement data output from a sensing device as measured on the test printout is received and analyzed, and information indicative of a cause for the print defect based on the analyzed measurement data output from the sensing device is output.

摘要： A method and apparatus are provided for evaluating the severity in a printed image of a repeating band print artifact. After electronically capturing the printed image, each of a plurality of patches taken from captured image is analysed to produce an artifact severity measure for the patch; an overall artifact severity value is then determined for the printed image from the patch severity measures. The analysis of each patch involves producing a spatial intensity profile across the patch substantially at right angles to an expected direction of extent of any repeating band print artifact present; a Fourier-related transform is then applied to the spatial intensity profile and the patch artifact severity measure generated by summing the resultant spatial frequency coefficients in a limited range about a frequency of interest.

摘要： In a method of automatically replacing undesirable pixels in an image, a local neighborhood of pixels is identified around an undesirable pixel. In addition, secondary neighborhoods of pixels are identified and feature values of the pixels contained in the local neighborhood and each of the secondary neighborhoods are calculated. The secondary neighborhoods having feature values within a predetermined range of the local neighborhood feature value are classified as candidates for pixel value replacement. Moreover, a replacement pixel value from at least one of the secondary neighborhoods classified as a candidate for pixel value replacement is determined and the undesirable pixel value is replaced with the replacement pixel value.
