Corner Features Extraction of Image Based on Orientation SUSAN Operator
The corner feature is an important character for image matching of the different sensors,the corner is defined as the position of very high curvature on image edge commonly.In order to meet practice need of image matching for imaging sensor with orientation,it is necessary to detect corner feature that is stabilization,credibility and orientation.In this paper the algorithm of orientation SUSAN corner detection is adopted,the method is the calculating region of SUSAN operation limited an appointed sector,so that corner feature is detected with orientation.Experiment indicates that this method is simple,practical and effective.
