Determination and Aggregation of Edge Elements

Figure 18 depicts a gray valued coded result of the gradient magnitude of EEs computed for the image region discussed so far. Aggregation of these EEs into straight line edge segments, superimposed to the corresponding region from the original image, yields Figure 19. The resulting ESs themselves are shown in Figure 20.
