An overview of the application of image processing technology for yarn hairiness evaluation

Abstract

Purpose This paper aims to overview the current status of development and application of digital image processing technology used for the yarn hairiness evaluation. Design/methodology/approach Digital image processing technology is one of the new methods used for the yarn detection, which can be used for the digital characterization and objective evaluation of yarn appearance. The comparison between the traditional detection methods and this new developed method was made and analyzed. Findings Compared with the traditional methods, image-based methods have the advantages of being objective, fast and accurate. Therefore, it was proved that digital image processing techniques should be a new trend in terms of the yarn appearance evaluation.
