Hi,
May i know how to calculate the percentage intensity difference between 2 image of the * DIFFERENT DIMENSIONS*. Then i need to apply this % of intensity different to another image of different size.

Why not size them to the same size with imresize() and then just subtract them and divide the difference by one of them? Or use immse(), psnr(), or ssim()? Or do you have some other special definition of how to define the percent variation?
