Automatic analysis of woven fabric weave based on notation

For identification of the basic weaves of the fabric from its notation,two methods based on autocorrelation function and Su index are proposed to extract the repeats in warp and weft directions of the notation to obtain the fabric weave diagram.By comparing the effectiveness and computational complexity of the two methods,Su index method is selected for recognizing the weave of the fabric from its weave diagram.During the recognition,the Su indices in warp and weft directions are calculated respectively.The repeats of warps and wefts can be achieved from the calculated results of Su indices and the woven fabric weave can be finally obtained.Actual examples proved that this identification method is effective.
