Thermal paint, paint that changes colour with maximum temperature, has a variety of uses within the automotive industry. The analysis of samples after exposure to heat is a task currently performed by humans. We present the current findings of our attempts to automate this procedure by means of image analysis. A framework has been developed within which colour is mapped to an RGB space curve which is a function of temperature. This models the context imparted by the physical process, as well as spatial context, and gives us better results than those obtained by using conventional image segmentation techniques.
