Abstract: The traditional method to design fabric weave is through making variations in heddles and cards on the weave pattern,which requires a designer who should have experience in it and has to do the boring operation as clicking with mouse one by one according to each variation.This article presents a new weave design method that is different from normal ones.It is based on the principle of image transformation technique,and starting from the existing weave patterns, transforms weave images via such technique as twisting,cutting,filling,etc.Then,recognizing of the transformed weave image is undertaken by computer and a new weave pattern with varied transformation characteristics is obtained.By selecting different transformation methods and parameters,this design method can get many new weave patterns based on the existing one in a minute.It is simple in operation and high-efficient in designing,thus providing a good way for dobby fabric weave design.
