Partitioning or segmenting an entire image into distinct recognizable regions is a central challenge in computer vision which has received increasing attention in recent years. It is remarkable how a simple task to humans is not so simple in computer vision, but it can be explained. To humans, an image is not just a random collection of pixels; it is a meaningful arrangement of regions and objects (Figure 1 shows a variety of images). Despite the variations of these images, humans have no problem interpreting them. We can agree about the different regions in the images and recognize the different objects. Human visual grouping was studied extensively by the Gestalt psychologists. Thus, Wertheimer pointed out the importance of perceptual grouping and organization in vision and listed several key factors Wertheimer (1938), that lead to human perceptual grouping: similarity,
