DETECTING 'YELLOW STAIN' IN WOOD USING SPECTRAL METHODS

Abstract

This paper deals with the detection of ‘yellow stain’ in wood samples using colour. We describe an investigation into the spectral properties of the stain and use the findings to design a detection system. We found that infected regions invariably differed from healthy regions in the 400nm to 450nm region of the spectrum. We developed a system based on an economical RGB camera and an optimised light source. The source consists of two narrow bands: one in the blue channel of the camera where the discriminative information is held, and one in the red channel that acts as a normalisation factor to remove the effect of the natural patterning of the wood. A simple classifier was used with the red and blue channels of the camera and produced results that agreed with our client’s subjective judgement.
