    Let say image_test is a gray image, for detail documentation of edge detection, read here
    image_test=imread('image_file_name.format')
    %............................example^ pic1.png
    image_edge=edge(image_test); %sobel by default
    imshow(image_edge);
    For Canny:
    image_edge=edge(image_test,'Canny');
    For Fuzzy edge detection, visit here, all explanation is there.
