I have an image of size 330x363 uint8. I am convoluting it with 11x11 filter using conv2. The resulting image gets padded with zeros from top (6 pixels), bottom (4 pixels), left (6 pixels), right (4 pixels). Is there a way to prevent this padding from happening? Is it a good practice to crop the resulting image after the convolution?

conv2(A, B, 'same') or conv2(A, B, 'valid')

I've already tried 'same' before but it did not work, as it also introduced zero padding of size 1. But 'valid' worked just fine! Thank you.
