Hi everyone. I'm unwrapping the phase of a hemisphere image, using MATLAB unwrap function. the image contains vertical lines. the function 'unwrap' works well for a constant surface but it doesn't for the hemisphere. there are some jumps in the unwrapped image.
I use the function in the form of:
UnwrappedImage7=unwrap(unwrap(PHI,[],2),[],1);
Do you have any sugestions to eliminate the jumps?
