Abstract

A review is presented of the WRONZ approach for measuring carpet appearance using digital image analysis. The emphasis in this paper is on practical aspects, and it highlights recent research findings, particularly the benefits of high-pass filtering. Var ious parameters that are considered to be necessary to fully characterize the textural properties of new and worn carpets are defined, illustrated, and discussed. Texture parameters include tuft definition, pile lightness, texture coarseness, directionality, coherence, tuft-size uniformity, and bright-spot density. The relative importance of these parameters in describing initial carpet texture and the changes in texture caused by wear depends on the kind of carpet being measured. Potential applications of the technology to quality control in carpet manufacture are now being explored with the cooperation of a local mill.
