Abstract
As a characteristic behavior of edge signal intensity, the strictly monotonic variation of intensity across an edge is employed to propose a new criterion for identifying edges beyond scaling. Instead of the usual local operator such as the gradient, we extend the directional derivative to define a nonlocal operator, in terms of which we can describe a new edge detection algorithm adaptive to the variation of edge width.
