Binary image operations using non-coherent optical techniques

摘要

Information can be extracted from two valued images (binary images) by performing logical operations in which a new image is created which is a function of the original image. To form this new image, shifting, storage, and logical operations are required. Cross-correlating an image with a “transfer function image” and thresholding the resultant cross-correlation image will perform the equivalent operations in a single step. Experiments demonstrating the technique have been performed.
