- if we shift an image, the output is also shifted equivalently shifted
- our visual systems are this
to prove
- for a system f→g, where g=(f*h), and we need to prove g’=(f’*h)
- express g’ in terms of f and h, with def of convolution (left side of statement to prove)
- express
(f' * h)with def of convolution (right side of statement to prove) - show equal
