To apply a Sobel X filter in MATLAB for edge detection, you can use the fspecial
and imfilter
functions as demonstrated below:

In the code above, we first load an image and convert it to grayscale. We then define a 3x3 Sobel X filter and apply it to the grayscale image using the imfilter
function. Finally, we display the resulting edge map using the imshow
function.
