One of the areas (outside of 3D-graphics) where GPUs can be very effective is image processing. Usually we have one or several images and want to change the input image in some way (or to combine several images). Besides, we can have two images and want to build a transition from one image to another. Image processing includes tasks such as image magnification/minification and image warping.
