| Abstract: | In the process of sorting wood, the image defect segmentation p｜ays an essential role. The accurate extraction of the defect profile will directly affect the accuracy of sorting. This paper discusses the method of extracting wood surface defect images, ap- plies OTSU algorithm combined with mathematical morphology to segment the defect image, and finally extracts the defect edge. Ex- periments show that the visibility and accuracy of the images are improved by OTSU algorithm and mathematical morphology. |
