摘要：Edge detection is considered to be fundamental step in the field of image processing and computer vision, particularly in the area s of feature detection and feature extraction. Detecting edges is a basic operation in image processing because an edge in an image usually refers to the boundaries between different regions and reflects a break in the continuation of any image characteristic. The purpose of this paper is convoluting original images (512x512) with the various edge detectors in presence of impulsive noise and analyse the results on the RGB planes distinctively to look for their performances in terms of PSNR as an objective parameter
