Image-based evaluation of seam puckering appearance

We present the development of an objective evaluation method based on the integration of X-illumination, morphological fractal analysis and Bayes classifier that aims at characterizing the seam-puckering appearance. The experimental results in our research demonstrate that a highly significant correlation coefficient can be achieved between the estimated grades and the techniciangenerated grades; the presented method is insensitive to the color/ texture of fabrics, thus showing the potential use of our newly developed method to evaluate the seam-puckering appearance objectively and quantitatively. © 2008 SPIE and IS&T.
