A new concept for on-line tracking and recognition in robot vision is presented. It uses the high speed Fourier transform properties of coherent optical systems but replaces the holographic filtering (hardware) by electronic processing (software) of amplitude and phase in the Fourier plane. The phase information is extracted by heterodyne detection. The 2-D moments of optical patterns can be determined by the same method.
