Edge Detection Using a Complex-Valued Directional Vector Representation
Conference paper
Abstract
Edge detection is a fundamental step in computer vision and image analysis. A new method using the modified Laplacian and position mask is proposed for edge detection of both gray-evel and color images. A directional field is computed by the proposed masks and edges are detected by additional simple mask operations. Edge detection results by the proposed masks are shown in comparison with those by Sobel, Laplacian of Gaussian (LoG), and Canny operators.
