i have a medical image (attached). I want to find the patches from two images(original and the deformed version of original) without the black background.
startCoord = [30,40];
centerCoord = [70,75];
patchSize = 32;
patchSourceImage = im(centerCoord(1)-ceil(patchSize/2):centerCoord(1)+ceil(patchSize/2)-1,centerCoord(2)-ceil(patchSize/2):centerCoord(2)+ceil(patchSize/2)-1);
patchTargetImage = locally_deformed_image(centerCoord(1)-ceil(patchSize/2):centerCoord(1)+ceil(patchSize/2)-1,centerCoord(2)-ceil(patchSize/2):centerCoord(2)+ceil(patchSize/2)-1);
Using this i want to find the displacment values from original and deformed image. MY question how should i determine my starting coordinate andcenter coordinate? My image if size 256*150.

I'm sorry, I really don't get what you are trying to do. You already have a center and start coordinate. Do you have displaced images that you are trying to align?
