Objectives: To compare different edge detection techniques for the effective performance results with respect to complex images. Methods: This paper compares and analyses the performance of diverse edge detection techniques for recent digital image processing like canny optimal edge detection, sobel operator, prewitt operator and LoG. Findings: Canny Optimal Edge detection (COE) technique provides better performance results under noise images or complex images when compared to other techniques. In COE the result of PSNR is high which helps to identify the effective edges.
