This paper describes a digital image processing system for the analysis of colour in wound images under clinical conditions. The system uses a 3CCD array digital video camera together with a colour scale for reference. The accuracy of colour assessment was compared with clinicians assessment of the amount of slough necrotic tissue in digital images. The system was found to be within the range of 10 in describing red hue values in red colour patches between different clinical sessions. There was agreement in 75 of the cases between clinicians assessment of the amount of slough and a computer assessment using digital imaging. However, colour may not be sufficient to describe wound appearance accurately.
