Abstract: Natural Surfaces Indexing based on their visual appearance is an important industrial issue for example in inspection and automatic goods retrieval problems. However due to the presence of randomly distributed high number of different colours and its subjective evaluation by human experts, the problem remains practically unsolved. In this paper it is presented some new features derived from a wavelet decomposition of the original images. This decomposition was applied to different models of colour representation and they were used different wavelet families and resolution levels. It will be shown that promising indexing results applied to marble surfaces can be obtained with a suitable combination of those parameters and using our proposed new features for indexing with very simple Euclidian distances.
