Abstract
Abstract Dynamic data generator circuitry is disclosed for use in an image analyzer system. The system includes a plurality of storage devices for temporarily storing a neighborhood in the image matrix comprised of a central data point and its surrounding points in the matrix. A transformation generator includes neighborhood contribution circuitry for operating on the values of each point in the neighborhood when they are loaded in the storage devices. The maximum value associated with any of the adjusted points in the neighborhood is provided as a transformation output signal. To aid in the maximum value selection process, the value of the central data point in the neighborhood is sensed and used to provide a correction value so that all of the adjusted data points in the neighborhood are within a particular range of values so that the maximum value selection circuitry may accurately identify the data point in the neighborhood truly having the maximum value associated with the image.
