A Comparison Between Enhanced Edge Detectors

Edge detection is a fundamental tool in computer vision. It is often used in image processing and feature extraction. Enhancing the edge detector can affect the overall result of the system. This research presents a comparison between commonly used edge detectors such as Canny, Sobel, Prewitt, Roberts cross, Laplacian of Gaussian, and the usage of Gabor filter as an edge detector. A morphological edge enhancement method is used as a post process to enhance the results of these edge detectors. Pratt’s figure of merit is used as an evaluation method. The results of the enhanced edge detectors have improved.
