Abstract
This closure provides image processing methods and apparatus for corner enhancing a digital image for rendering on an image output device. According to an exemplary method, the method determines whether or not image pixels are associated with a corner as a function of the USAN values generated for the image pixels. Subsequently, one or more pixels associated with a corner are modified to render a corner enhanced image.
