This paper proposes the weighted Gabor gradient algorithm based on the analysis of the characters of Gabor wavelet. The new method can obtain the more accurate direction of the gradient than the traditional gradient operators. And a new comer detecting algorithm based on the multi-scale weighted Gabor gradient is proposed. Experimental results with some synthetic and real images show that this new algorithm detects the comer more efficiently

locates the comer more accurately

and restrains the noise more effectively than the two classical comer detecting algorithms.
