Abstract
The present invention is a method for processing color image data to determine if a target pixel is within a border region near an interface. The method begins with the identification of a target pixel within the color image data and then determines if the target pixel is a black or a color pixel. If the target pixel is a black pixel, the method collects a first set of pixel statistics from a first window comprising the target pixel and pixels surrounding the target pixel and analyzes the first set of statistics to determine if the target pixel is within an N-pixel wide black border region near an interface. If the target pixel is a color pixel, the method collects a second set of pixel statistics from a second window comprising the target pixel and pixels surrounding the target pixel and analyzes the second set of statistics to determine if the target pixel is within an M-pixel wide color border region near an interface.
