A Modified Gradient Technique for Image Analysis.

Abstract

The modified gradient operation considered in this report takes the product of four conventional gradient operations in four different directions. Such modified procedure is shown by extensive computer results to provide great improvement in noise reduction and boundary extraction over the conventional gradient operation. Furthermore, the procedure is computationally simple and insensitive to rotation of images. Computer results of modified gradient operation followed by image compression are also presented. (Author)
