Method and apparatus for pattern recognition and detection

摘要

An image analyzer system employs at least one neighborhood transformation stage for analyzing groups of neighborhood pixel values and selectively transforming the pixel values as a result of the analysis. In one embodiment, the center pixel in the neighborhood is changed to a programmable transformation value if it and its neighboring pixels have particular values. Preferably, the stage includes a programmable memory loaded by a central controller which is utilized to determine whether neighboring pixels of particular values are configured in a preselected pattern. The stage may also include another programmable memory for assigning selected values to the digital signals depending upon their original values as they enter the stage.
