Importance of Edge Detection in Modern Era

Abstract

We know that the edge is a fundamental thing of any object. There is no object in this world without edge. Sometimes we can say edge is also known as a corner of an object. We can create any shape of object with the help of the edges. If we look into technically, an edge may be defined as a set of connected pixels that forms a boundary between two disarrange regions. Edge detection is a method of segmenting an image into regions of conclusion. That’s why we can say that the edge detection is also known as corner detection or shape detection. If edge is detected shape is also detected. Edge detection or corner detection plays very important role in digital image processing and practical aspects of our life. In this report, we studied various edge detection techniques as Robert, Sobel and Canny operators.
