A Review and Performance Analysis of Image Edge Detection Algorithms

Abstract

Edge detection is the fundamental operation of digital image processing and applied in many fields like industrial, medical, satellite, agriculture etc. According to this growth of edge detection applications, many researchers and scholars are interested to develop the edge detection algorithm by using various techniques. This paper illustrates the review for what are the novel techniques are used for the edge detection, which operators are mostly used by them and how they get the accurate results to compare with existing methods. It also discussing the performance analysis of most commonly used edge detection operators such as Canny, Laplacian Gaussian (LoG), Sobel, Prewitt and Roberts,. Finally the accuracy, PSNR (Peak Signal to Noise Ratio) and execution time are tabulated and realize the most precious and fast computed edge detection method is uncovered.
