Textile Inspection, Fast Fourier Transform


In this paper a automated analysis system for defect de tection in the print process of flocked fabrics with repet itive patterns is presented. This process represents a less computationally complex method than the detection of any type of pattern in the print process. For this reason, this problem can be solved using a personal computer (PC) in specting 100% of the production that fulfill the require ments of repetitive patterns. This system will be extremely useful for companies which produce repetitive pattern tex tiles in large quantities. The implementation of a prototype system, based on the Fast Fourier Transform, will be de scribed.
