摘　　要：本文从纹理的图形参数化表征和综合的思想出发，提出了一种方向性纹理的多通道分析模型．分别从空域和频域研究了纹理图像的各向异性及各向同性特征，并导出了确定纹理主控方向的有效计算方法，和残余图像的随机场模型逼近．实现了纹理场的参数表征．该模型具有灵活、高效的优点，具有广泛的适用性．实验结果证实了该方法的有效性．This paper introduces a multi-channel model for oriented texture analysis based on the idea of graphical parameter representation of texture. The anisotropic and isotropic features in spatial and frequency domain are studied respectively, and the algorithm for determining the dominant orientation of texture and approximating the remain image with stochastic field model is developed. The paper also implements the parameter representation of textural field. The experiment results show that this model has the advantage of flexible, efficient and wide suitability in many fields.
