| 摘 要： | 纹理图像被视为基本微模式的线性组合．拓扑图格独立分量分析首先被用来学习图像基，然后根据生成模型，通过变换图像基获得基本微模式．最后给出了其两个应用例子：从微模式中提取基本视觉元素，并提出了相应的算法；将学习获得的分离基视为滤波器，实现其纹理分割．对比实验分析表明，该算法可取得活意的分割结果．

| Abstract: | This paper treats texture image as a linear superposition of a group of fundamental micro-patterns. The topographic independent component analysis is employed first to learn the image bases, and those mixing bases are then transformed into micro-patterns, according to the generative model. Two examples of applications of image bases are illustrated finally. One is to extract the fundamental visual elements from micro-patterns, and the other is texture segmentation by using the learned unmixing bases as filters. Experiments on mosaic texture images show that the segmenting results are satisfactory. |
