System for processing textured images, texture analyser and texture synthesizer

摘要

A system (22) for synthesis of textured images, comprising a texture analyser (24) and a texture synthesizer (28). The texture analyser (24) comprises an analyzing neural network (30) which learns to characterize a texture by calculating synaptic coefficients (Cab), utilizing at least one proximity function which characterizes a neighbourhood around pixels of said texture. The texture synthesizer (28) comprises a synthesizing neural network (40) which receives the synaptic coefficients (Cab) thus calculated and which, utilizing a relaxation mechanism, synthesizes a replica of the texture learned. The neural networks (30), (40) may have a tree-type structure.
