Abstract: In order to simplify the regional design process of Jacquard regions in warp knitted fabrics, the automatic regional identification method is proposed in connection with the texture characteristics of various regions, particularly the difficult situation in mesh region classification. First median filtering is used for noise elimination in the original image. Second wavelet transform method is adopted to extract different fabrics regional texture features. Then in the case of knowing the Category number, K means clustering method is used to segment these texture features. Experiments show that the method has a good effect, Jacquard warp knitted fabric which with two or more regions can be distinguished in supervised and automatic manner, and the method is adapted to the mesh regions with better regional consistency and edge accuracy.
