视差检测:简单细胞、复杂细胞及能量模型

Disparity Detect: Simple Cell, Complex Cell and Energy Model.

立体视觉信息的处理在于皮层双眼性细胞的活动． 皮层中简单细胞对视差的编码方式被认为有两种： 位置差（ｐｏｓｉｔｉｏｎ ｓｈｉｆｔ） 和相位差（ｐｈａｓｅｓｈｉｆｔ） ， 但简单细胞并不适合作为视差检测器． 对一些复杂细胞的视差响应特性的生理研究， 发现复杂细胞是一种比较适合的视差检测器． 模型的研究提出基于这类简单细胞的复杂细胞能量模型， 可以很好的检测视差，

The action of binocular cells in visual cortex is the foundation of information process of stereopsis. The disparity encode mechanism of simple cells are divided into two groups, one is position shift, the other is phase shift, but simple cells are not suited to act as disparity detector. On physiological study of some complex cells, people find some complex cells are ideally suited as disparity detector. A complex cell energy model based on these simple cells was provided. Mathematical analysis and computer simulation indicate that this model can explain many physiological data.
