| 摘 要： | 人眼的视觉信息采集是非均匀的。这种特征和注意力机制确保了人类视觉系统在信息处理方面的优先性。首先介绍了对数极坐标映射，然后基于人类视觉系统的构造，提出了非均匀映射模型的构造规则。基于此规则，以线性模型为例进行了应用性研究。扩展了非均匀映射模型的范围，促进了空间变分辨率视觉理论的进一步发展。

| Abstract: | The visual information gathering of human eyes is non-unlformed. This attribute and attention mechanism enables human vision system predominant in information processing. Firstly this paper explores the log-polar transform; secondly it puts forward the general rules of constructing the mapping model inspired by human vision system. Finally based on the rules, the model is deducted and validated. This research not only extends the mathmetic model of non-uniformed mapping, but also promotes the development of the space-variant vision theory. |
