In the process of edge detection based on mathematical morphology，the structural elements of different shapes/scales play different roles in noise filtering and keeping edge details intact. An adaptive edge detection algorithm based on multi-shape /scale structural elements was therefore proposed. Where the image edge was extracted using different directions/sizes structural elements. Then, the weight factors were determined adaptively by computing the information entropy so as to integrate the edges detected by multi-shape and multi-scale structural elements. Experimental results showed the proposed algorithm can suppress the interference of noise more effectively in comparison with several classical edge detection algorithm,，thus improving the detection accuracy and robustness of different images.
