6-2 Gray Level Corner Detection

In this paper the analysis of gray level corner detections has been carried out. The performances of cornerness measures for some corner detection algorithms are discussed. This paper presents a new approach for corner detection called the GradientDirection corner detector which is developed from the popular Plessey corner detector. The GradientDirection corner detector is based on the measure of the gradient module of the image gradient direction and the constraints of false corner response suppression.
