摘 要
鉴于立体图象对中特征的视差确定是计算机立体视觉研究的一个难点,因此在FACADE初级视觉理论的框架下,针对生物视觉系统对不同方向特征的不对称处理,结合细胞动力学方程实现了一种基于各向异性竞争的双目滤波器。这种改进了基于各向异性竞争策略FACADE系统,由于更有利于将双目特征匹配还原为细胞活性的自组织活动,因此获得了真实场景中的视差分布。

Abstract
In the field of computer vision,it's difficult to get the disparity of features from stereo images.In this paper,a binocular filter based on anisotropic competition which adapted from FACADE theory to find disparity of features is proposed.Binocular filter use cells activity to represent the disparity distribution of features.There is competition between cells before the disparity distribution of features is acquired.Because of the horizontal bias of “eyes”configuration in binocular vision system,features with different orientation must be processed differently. Anisotropic competition is used in order to consider features with different orientation in a uniform way.The method of anisotropic competition better the performance of FACADE model by favoring the self-organization of cell activities.This approach is much different from the traditional method of matching the elements in the two images,which provides a different view of computer vision research.
