Abstract: A digital image processing system provides convolution, correlation and normalized correlation functions, without per-pixel multiplication operations, utilizing factorization and moment generation. A first memory array is addressed by image pixel values, and a second memory array is addressed by template pixel values. Logic and control elements increment the array element addressed by the image pixel value, and add the image pixel value to the array element addressed by a corresponding template pixel value. The resulting sums in the first and second arrays are processed to generate convolution and correlation functions.
