Local Orientation, the edges. We concentrated on the detection of edges, but we did not consider how to determine their . Orientation is a significant property not only of edges but also of any pattern that shows a preferred direction. The . of a pattern is the property which leads the way to a description of more co

Texture,enabled us to distinguish objects not only because of their gray values but also because of the orientation of the patterns (compare figure 7.1). Real-world objects often carry patterns which differ not only in their orientation, but also in many other parameters. Our visual system is capable of rec

Parabola

Segmentation, us to distinguish them from other objects and from the background. The next step is to check each individual pixel whether it belongs to an object of interest or not.
