A post-processing system for an optical correlator automatically detects and ranks peaks in the correlation image. An array of input buffers each receive pixels from a predetermined region of the image from the correlator camera. An array of peak detectors search the image pixels in each region for correlation peaks exceeding a predetermined threshold figure of merit. For example, each peak detector can be convolver array and a local maximum detector. The peak detectors generate a report entry for each such correlation peak that contains the figure of merit and location of the peak within the image. Results sorting and reporting means collect and store the report entries from each peak detector. The report entries are sorted by their figures of merit and reported to the host computer system.
