Changes in the appearance of carpet pile due to mechanical wear may be evaluated with respect to changes in global image properties, ie those based on one-dimensional characterizations of the intensity surface. This paper describes the application of grey scale image analysis to the measurement of microtexture variation and roughness or relief. An attempt is made to characterize microtexture with intensith mean, variance, skewness and spatial co-occurrence. Surface relyief is quantified as normalized intensity area and fractional dimension. The samples show that simple mechanical wear generally entails a loss of relief and variation, but carpet construction has an improtant effect on the observed trends. Intensity mean and fracion dimension are promising candidates for automated evaluation of carpet appearance.
