Knitted Fabric Surface Density Measurement by Image Processing Using of Smart Phone Technique

Abstract

In this paper ,A proposed image operation method of measuring the stitch density (course per inch and wale per inch) of a knitted fabric has been developed in this research. The stitch density of a knitted fabric measured by proposed image method which captured by a smart phone technique. The measured stitch density to be examined by the said algorithm. The method was tested using 5 knitted fabric samples with different densities. In order to validate the proposed method, The results were compared with the stitch density directly measured by conventional ( The ASTM standards methods ) methods. It has been found that the results between conventional and proposed image method are significant (with 0.95 & 0.99 significance value) with 97.30 %.
