how to do segmentation of a woven fabric image

I am doing project on fabric texture analysis.In that i have to identify weave pattern.first step of my project is to detect crossed area of a warp and weft yarn. In order to detect crossed area i have to find spatial domain integral projection of warp and weft directions. In that integral projection curves i have to find local minima and by finding this local minima i have to find warp and weft separation areas. by using this i have to segment the woven fabric image. so i need code for this thank in advance
