Abstract :
This study is to compare how Canny and Sobel Operators can be used as edge detection technique for various logo images. The main process involved Sobel and Canny edge detection techniques using captured logo images and logo images from internet. The images manipulated by median filtering to remove noise and Otsu´s method is used to determine threshold value. The result shows that both operators have their own advantages and disadvantages to be used as edge detection aid for logo images.
