An Iterative Gradient Edge Detection Algorithm.

Abstract

Local gradients yield valuable directional information, which is useful in edge detection in digital pictures. Parallel iterative algorithms can be devised to process the edge vectors derived from the gradient. The resulting output consists of thinned edges which may be tracked very quickly. Examples of pictures processed by this method are given, and suggestions for further modifications are made.
