Abstract

. Skin colour detection is an often used cue in human motion tracking, especially in face tracking. Skin colour detection is orientation invariant and fast to process. In this paper skin colour is modelled based on a reectance model of the skin, knowledge about the camera parameters, and the spectrum of the light source. In particular, the location of the skin colour area in the chromaticity plane is estimated for dierent light sources, given known camera characteristics. The model is empirically validated. It has application in adaptive segmentation of skin colour and may have application in the estimation of the colour temperature in camera images containing skin colour.
