Patent ID: 7085422

Claim:
A method for image separation of an image, the image comprising pixels, the method comprising the steps of: identifying kernels reflected by at least one of the operators selected from the group consisting of: P(x−w,y)−P(x,y)>t AND P(x+w, y)−P(x,y)>t ; and P(x, y−w)−P(x,y)>t AND P(x, y+w)−P(x,y)>t ; and P(x+d, y+d)−P(x,y)>t AND P(x−d, y−d)−P(x,y)>t ; and P(x−d, y+d)−P(x,y)>t AND P(x+d, y−d)−P(x,y)>t; associating said kernels with a first layer; and classifying as a second layer, said pixels which are not associated with said first layer.
