ABSTRACT:
A method for is provided for antialiasing a computer graphics image using filtering. The method comprises the steps of defining a plurality of regions having samples from pixels in the computer graphics image, where the regions are associated with a pixel of interest and adjacent pixels to form an antialiasing filter. Another step is determining a contrast for each region. A further step is blending the regions that form the filter based on the contrast for each region.
