Abstract
Image analysis method for determining pigment levels in fabric and yarn material. A sample fabric or yarn is illuminated by a source of visible light and a selected field area of the material is recorded then digitalized and stored in a video memory device. The digitalized field area is resolved into discrete segments or pixels having different intensity or gray level values. A frequency distribution in the form of a histogram of gray level values is plotted, and the resulting histogram is interpreted to determine pigment levels in the material sample.
