Step's that we have followed;
1. Computed the f (x; y) * h(x; y) in the spatial domain. (Spatial_domain.m)
2. Compute F(u; v) . H(u; v) in frequency domain. (Frequency_domain.m)
3. Verify your codes by performing filtering in both spatial and frequency
domains and check the results.
Are you getting the same results?
