Simultaneous region and edge segmentation of infrared images using non-maximal suppression for edge thinning
John F. Haddon, James F Boyce · 1990
A cooccurrence space is defined by utilising the combinations of pixel strengths defined by a Canny edge operator. A region and boundary segmentation derived from this space is first edge thinned by non-maximal suppression and then hysteresis is used as a post-processing step to improve the edges. The distributions in cooccurrence space define the thresholds employed in the hysteresis post-processing.
