The lightness changes due to dyeing, washing and exposure to light treatments are studied. These properties are measured by using the changes in the intensity levels of the fabrics image and the L* obtained by a spectrophotometer. For each case, analysis of variance (ANOVA) is carded out and the correlation between the intensity level and L* is computed. This study also investigates the use of angular power spectrum (APS) to quantify the variation in fabric surface protrusion due to washing.
