Abstract:

The paper first describes the watershed algorithm and solves the problem of the over-segmentation from the watershed algorithm by using the mark watershed transform; then wood defect image is treated with algorithm; finally the comparison is made between the original image and the edge image detected. The result showed that the wood defect image could be segmented with the mark-controlled watershed this algorithm and the defect edge image be exactly detected. Moreover, the treatment also provided the convenience for the following treatment such as pattern recognition.

Key words: watershed algorithm, wood defects, edge detection, over-segmentation
