Using computer image analysis, we evaluate the degree of wrinkling appearance as indicated by the AATCC replica rating system and investigate the effects of color fabric patterns on wrinkling. The angular second moment, contrast, correlation and entropy as textural feature parameters were extracted from the co-occurrence matrix for each gray level intensity of the red (R), green (G) and blue (B) images obtained from decomposition of the color image in red-green-blue. The fractal dimension was also determined from the relief of the curved surface of the R, G and B images. Using computer image synthesis, the first grade of surface wrinkling of the AATCC replica plates was imposed on eight fabrics: one control fabric (plain green) and seven fabrics with different patterns. Results indicate wrinkling appearance can be reliably evaluated using computer image analysis. We discussed the effects of color patterns on wrinkling appearance in terms of textural feature parameters and fractal dimension.
