Abstract: This paper compares the performance of different edge detection methods like Sobel; Prewitt; Roberts; Canny; Laplacian; Laplacian of Gaussian with Gabor filter on number of images. It has been concluded that in case of natural images a Gabor filter yields better results than other operators but in case of medical images like CT; PET; MRI; the Canny operator shows better results as it provides fine details of an image.
