Paper Abstract

A digital image processing approach to develop an automatic method for the objective measure of some thread parameters in a non closely-woven fabric is presented. The parameters addressed by this method are thickness, periodicity, regularity, area of holes between threads and cover factor. Applied techniques range from image thresholding for the segmentation of the threads from the background, to morphological operations such as skeletonization and non-lineal filters. They are successfully applied to segment vertical and horizontal lines describing the geometry of the threads. The mentioned parameters are derived from further labeling of the skeletonized images.
