Prewitt operator for edge detection

The Prewitt operator is one of the first algorithms for edge detection by gradient transform. It is developed by Judith M. S. Prewitt and is a popular tool for image analysis.

Gradient Non-Maximum Suppression

The gradient Non-maximum suppression also known as edge thinning is a process of extracting thin, one pixel wide object’s contours. This process follows edge detection as a post processing step. The non-maximum contour suppression is one of the main steps of the popular Canny edge detector.
