Abstract
The contents of an image can only be revealed when we analyze the spatial relations of the gray values. If the gray value does not change in a small neighborhood, we are within an area of constant gray values. This could mean that the neighborhood is included in an object. If the gray value changes, we might be at the edge of an object. In this way, we recognize areas of constant gray values and edges.
