Abstract: To improve the intelligent analysis and design technology of warp knitting jacquard fabric, a new way of texture segmentation and contour extraction based on wavelet-transform and canny operator is proposed in this paper. Firstly making use of the wavelet-transform which has the ability of orientation and multiresolution, the algorithm decomposes the low frequency part of the fabric image in a way of pyramid-structure. Secondly from the biggest level after decomposition, the image is automatic clustered and segmented with the information at the next level. Lastly the texture’s contour of image is traced and extracted through the method of canny operator. The results show that this algorithm is a feasible way for jacquard fabric, and it supplies a theoretical platform for subsequent research.
