Hi Ali,

I understand you would like to apply “Sobel” and "Prewitt” filter on an image. I would suggest you use the “edge” function in MATLAB. For using the function, you will require the Image Processing Toolbox.

I = imread('coins.png'); 
BW1 = edge(I,"sobel"); 
BW2 = edge(I,'prewitt'); 
tiledlayout(1,2) 
nexttile 
imshow(BW1) 
title('Sobel Filter') 
nexttile 
imshow(BW2) 
title('Prewitt Filter') 

You can refer to the “edge” function documentation using the following link.

Hope this will help in resolving the issue!
