WebMar 3, 2024 · 4) If you want to use imwarp to apply a geometric transformation to an image and reference the output image to the coordinate system of another image, then you will need to use the 'OutputView' option of imwarp to guarantee that the output image is the same size as the fixed image. Again, this is shown in the examples for imregtform.
