Abstract :
According to the theory of mathematical morphological, edge detection operators and characteristics of wood decay image, a multi-structure element multi-scale edge detection algorithm based on mathematical morphology is proposed. The image is filtered by an alternative-order morphological corrosion-expansion filter with a multi-scale element, and the edge information is obtained using multi-structure elements open-close operation. Canny operator is used to extract the edge of the decay image. Experimental results show that the proposed algorithm is insensitive to noise and is efficient in edge detection.
