Image Registration And Differencing By Coherent Optical Pattern Recognition
Abstract
The role of coherent optical pattern recognition techniques in image registration for track assembly and target discrimination applications is addressed. Use of optical pattern recognition on visible and simulated infrared mosaic imagery is found to have adequate accuracy to merit further attention. A frequency plane correlator using weighted matched spatial filter synthesis techniques was found to be a most optimum and flexible optical image registration system.
