Abstract
A method for assigning background pixels an appropriate color to fill all remaining background pixels by a computer after standard paint and overscan techniques to prevent and reduce artifacts. The method includes computing an initial mipmap level and keeping track of which pixels are background pixels. Four pixels at a subsequent mipmap level correspond to a single pixel at a higher level. If the four pixels at the lower level are background pixels, then the single pixel is also a background pixel and a corresponding color is used. Otherwise, the color of the single pixel is the average of non-background pixels.
