Hi Selva Karna,

The canny edge detector works on 2D images and not 3D images, you will have to convert the JPEG image to grayscale image using rgb2gray function and then run the edge function on it. To view the final result you can use imshow function

I = imread('board.tif'); % replace board.tif with name of your image 
I = rgb2gray(I);
I = edge(I,'canny');
imshow(I)
