![]() At last, different patterns of Li brocade design are briefly analyzed according to the digital characteristics. The extracted contour features were processed by means of morphology, and digital characteristics of contours are obtained by invariant moments. First, edge detection was made on the design patterns, and then the morphological closing operation was used to smooth the image, and finally contour tracking was used to extract the outer contours of Li brocade patterns. ![]() The meaning of Li brocade patterns was analyzed and the shape feature extraction techniques to original Li brocade patterns were advanced in this paper, based on the contour tracking algorithm. ![]() ![]() Hainan Li brocade skills has been listed as world non-material cultural heritage preservation, therefore, the research on Hainan Li brocade patterns plays an important role in Li brocade culture inheritance. ![]()
