This code implements the well-known Chan-Vese segmentation algorithm from the paper "Active Contours Without Edges." This technique deforms an initial curve so that it separates foreground from background based on the means of the two regions. The technique is very robust to initialization and gives very nice results when there is a difference between the foreground and background means. This code uses active contours and level sets in the implementation. It could also serve as a good framework for implementing all kinds of region-based active contour energies. 1.) Download 2.)

视觉神经科学中一个重要的研究方法就是建立初级视觉系统功能与自然图像的统计特性之间的关系，通过对自然图像的有效编码（稀疏性）可以模拟初级视觉皮层的一些基本属性，包括简单、复杂细胞的感受野，细胞的空间组织结构等。本课题旨在研究如何建立一个高阶神经网络结构，通过学习过程稀疏的表示复杂细胞对自然图像块的响应，进而实现对图像轮廓的编码以及模型自上而下的推理。-use ica and gabor filter to simulate the visula system of human
