An image edge detection method is proposed according to the characteristics of remote sense gray images based on the small scale mathematical morphology. The non maximal operation is applied to extract edge points through analyzing the extracted results under different scales. Experimental results by using this remote sense image edge detection are presented. A better sense image is achieved through this method compared to other detection methods.
