Research on Optical Image Processing
Abstract
Research on computer processing of optical information included coding, enhancement and detection using monochrome and color images. A bandwidth reduction and tolerance to channel errors for monochrome images have resulted from digital image transforms. Sample reductions on the order of the ratio 5 to 1, compared to conventional PCM coding, have been reported for transform coding of monochrome images. The generalized Wiener filtering technique has been applied to the enhancement of images. A new measure of similarity between images has been developed which is proposed as a useful detection criterion. The measure has information theoretic properties and, with proper image normalization, is the entropy function. Five manuscripts have been submitted for publication and eight papers were presented at various conferences/symposia.
