An edge is a boundary between an object and its background.If the edges in an image can be identified accurately, all of the objects can be located and basic properties such as area, perimeter, and shape can be measured.Since computer vision involves the identification and classification of objects in an image.So for this purpose edge detection is an important tool.This technique helps to localize the significant variants of the graylevel images and to identify the physical phenomena.This information is very useful in image registration, compression, enhancement and restoration, reconstruction, understanding, recognition.
