Hi,
I wanted to know if it's possible to apply the imwarp to only a part of an image.
Let's suppose I have a really huge image, but I'm interested in only a small part of it. What I'm doing right know, is to apply the imwarp to all the image, and then cut the part in which I'm interested in, but I have problems with the space needed from Matlab.
If I crop the image before, and then apply the transformation, I will not obtain the same result as the previous method.
How can I crop the image and then apply the imwarp to the cropped part "as if it was with the whole image"?
Thanks

What is the problem with the space needed? I don't think an image takes a lot of space.
