在分析分形维和马尔可夫随机场两种主要纹理模型法的基础上，提出了先用马尔可夫随机场方法进行纹理分类，再用分形维方法对那些具有相同马尔可夫随机场模型及参数值相近的纹理影像进行分类的方法。该方法不仅能提供出影像纹理的纹理基元，还能给出影像粗糙性、自相似程度，减少了纳伪误差。 On the basis of analyzing the two main texture model methods of fractal dimension and Markov random field, this paper proposes to use Markov random field method to classify the texture first, and then use the fractal dimension method to analyze the model with the same Markov random field model and parameters Texture image similar to the classification method. This method can not only provide the texture primitives of image texture, but also give the image roughness, the degree of self-similarity and reduce the supremacy error.
