Should be the same directory as the generated executable or should be the source directory of opencv_contrib and then rebuild the opencv library?

It was because the the images didn't had the same size, width and height. The pyramid images are just a series of scaled down images of the original images, and if the original images didn't had the same size, any two corresponding pyramid images will also be of different size.
