Abstract
Edge extraction is an essential part of image processing. In digital image processing there are several optical methods for properly obtaining image e dges. We propose a method of image edge extraction and enhancement by using a lens-based optical setup, the image, and its inverted form. The inverted and the noninverted images help here to obtain the image edges. (C) 1998 O ptical Society of America.
