Abstract
A method and apparatus for simultaneously correlating a mask to a series of shifted positions of an image. A series of bits from a field representing an image are supplied to a number of buffer registers. A number of overlapping combinations of bits from the buffer registers are simultaneously compared with the mask bits and a signal is produced indicating the results of such comparison for each of the image bit combinations. Algebraic functions are applied to the separate combinations to relate individual comparisons. A statistical analysis is performed to determine a best fit of an image to a mask.
