Texture analysis by a perceptual model

A hierarchical set of operators for texture analysis is presented. The method used is to code the local frequency resonance of these operators but not their simple responses. Therefore, the texture features obtained are stable. The operators fulfil the conditions described by J.P. Crettez (1984) in his work on the visual system model. The procedure is used to automatically determine the resolution of homogeneous texture, the resolution being the minimum window size capable of giving stationary features. All the samples of suitable size then have the same signature coding the local feature of texture
