| Abstract: | Gauss - Markov random field model(GMRF) is introduced to fabric texture analysis. Incomplete Cholesky Conjugate Gradient Method is utilized for estimation of GMRF model parameters which are used as fabric texture features in texture analysis. After the model parameters have been acquired, they are used for synthesis of the crude fabric texture. Experiments show that the resulting simulated fabric texture image shares almost the same visual effects with the corresponding real fabric texture image. The fact proves the algorithms presented in the paper and the rationality of GMRF for texture modeling of fabric. |
