9.3.5 Boundary Finding Based on Edge
Detection and Linking
As discussed earlier, edges are closely associated with the boundaries of objects
in an image. Pixels exhibiting the required characteristics are known as edge
points. Edge points can be detected and used to establish the boundaries. We can
