Overview and Comparative Analysis of Edge Detection Techniques in Digital Image Processing
نویسنده
چکیده
Edge detection is one of the most frequently used operations in image analysis. If the edges of images could be recognized accurately, all of the objects can be located efficiently and performance can be measured easily. It reduces the complexity of image processing algorithms by reducing the amount of data to be processed .The quality of image is affected when there is an jump in intensity from one pixels to the another. Thus important objective is to detect an edge while preserving the important structural properties of an image. In order to analyze various edge detection techniques , comparative analysis of these techniques based on certain parameters like type of edge, edge localization, nature, cost, role etc are discussed in this paper.
