ABSTRACT
Digital image processing deals with digital images with the help of a digital computer. It is used in the medical field, remote sensing, machine vision, image sharpening and restoration, color processing, pattern recognition and microscopic imaging. It comes under the field of signals and systems but focuses partially on images. In image processing, edge detection is used to acquire data from the frame to extract its features. It divides an image into a matrix of pixel values which are compared with their respective neighbour values to examine a significant discontinuity. This paper proposes the algorithm for the implementation of sobel edge detection using Matlab thus reducing the complexity of edge detection concept.
