    Abstract: A method for processing an input image includes applying one or more transformations to the input image, whereby different shifts are applied to different pixels in the input image, so as to generate an output image. A region containing content of interest is selected in the output image, and the region corresponding to the selected region in the output image is located in the input image. The content of the located region in the input image is substituted for the content of the selected region in the output image.

    Abstract: A method for processing an input image (20) includes applying one or more transformations (50) to the input image, whereby different shifts are applie d to different pixels in the input image, so as to generate an output image (Fig. 3). A region (22) containing content (24) of interest is selected in t he output image, and the region corresponding to the selected region in the output image is located in the input image. The content of the located regio n in the input image is substituted for the content of the selected region in the output image.

    Abstract: A method for binarizing a gray-level input image including a plurality of pixels having respective gray-level values. A lower threshold and an upper threshold are determined. A first binary value is assigned to the pixels in the gray-level image having gray-level values above the upper threshold, and a second binary value is assigned to the pixels in the gray-level image having gray-level values below the lower threshold. The pixels in an intermediate group having gray-level values between the lower and upper thresholds are processed so as to determine optimal assignments of the pixels in the intermediate group to the first and second binary values.

    Abstract: Image processing apparatus is disclosed for locating labels on images of parcels comprising: means to generate and store in digital form an image of the parcel comprising pixels arranged in rows and columns; classification logic for classifying each pixel as either a label pixel, a background pixel or neither, based on the pixel colour; segmentation logic for reclassifying each pixel as either label or background based on its original classification and the classification of pixels in its neighbourhood; and identification logic for identifying the boundaries of regions in which all pixels are classified as label pixels.

    Abstract: A set of stored digital representations of numbers having an estimable error probability distribution and at least one known arithmetic relation between the numbers which can be expressed as a sum, difference or equality is corrected. The invention finds particular, but not exclusive, application to the correction of optical character recognition (OCR) results. Hidden Markov Model optimisation logic is employed for finding the most likely path through a set of states in accordance with probability functions recording the likelihood of transitions between the states giving rise to a set of event-related observations. The states are possible accumulated totals generated by adding or subtracting ones of the numbers to or from an initial accumulated total, addition or subtraction of the numbers to or from an accumulated total or equality of an accumulated total with the numbers are the events causing transitions from state to state, the digital representations are the event-related observations, and the error probability distributions are the probability functions.
