Abstract
An image processing method takes advantage of the recursive rendering capabilities of graphics hardware devices to blur images in real-time, without a significant amount of computational precision. The image blurring method makes copies of the image to be blurred, transforms the copies using different transformation amounts, and then averages the transformed images together into a blended image. This general process is repeated a predetermined number of times, using the blended image in the subsequent steps, to generate a blurred image.
