There are many motif elements containing certain features in traditional pattern which are useful to generation style pattern. It is difficult for the present method based on the edge and regional segmentation algorithm to obtain there elements and distribution information. Taking Xinjiang pile blanket for example, an interactive segmentation algorithm is proposed based on a regional tracking. First, template operator is defined, and motif elements are selected, through adjusting the parameter of template operator. Then, by introducing the symmetrical criterion of motif element, the problem of elements redundancy and overlapping is solved. The simulation results show that the proposed algorithm can satisfy the symmetrical fabric design segmentation and extraction.
