Abstract
Image processing sections and associated circuitry for generating signals indicative of the centered moments of a sliding submatrix window of signals located within a larger image matrix are disclosed. The processing sections include registers for storing signals indicative of the columnar sums of the signals within an intermediate submatrix of signals and for storing the sum of a subset of the columnar sums that is thereby indicative of the sum of the signals within the sliding submatrix window and, further is equivalent to an uncentered moment of the signals within the sliding submatrix window. The signals stored in the registers are continuously updated as the sliding submatrix window is sequentially moved within the image matrix. The associated circuitry combines the uncentered moment signals to produce centered moment signals.
