WebRe: how to upsample an image?! The function 'upsample' upsamples the image but inserts zeros in the extrapolated regions. This is the reason you notice checkered appearance in the image as the value '0' gives no (or dark) luminance. Try repeating the previous values instead of inserting zeros. I can give you a function to do this if you want it ... Webresample Function.
