Topological representation for matching coloured surfaces
Samuel Oluwadamilare Olatunbosun, Geoff R. Dowling, Tim J. Ellis · 2002
This paper discusses the problem of trying to distinguish multi-coloured objects which share similar colours. It introduces the colour region adjacency graph (CRAG) which describes the arrangement of colours on an object's surface followed by a graph matching procedure to recognise like and unlike objects. The paper also shows how the CRAG representation can be used to locate a model in a test image.
