Edge detection serves as a pre - processing step for many image processing algorithms such as image enhancement, image segmentation, tracking and image/video coding. The edge detection is one of the key stages in image processing and object recognition. Edge detection is a basic operation in image processing, it refers to the process identifying and locating sharp discontinuities in an image, the discontinuities are abrupt changes in pixel intensity which characterize boundaries of objects in a scene. The pro posed system we use canny algorithm, in canny edge detection can produce good detection of the edge with the thin and smooth it’s very useful for further study of segmentation.
