本文概述了视觉感受野的规范性理论。我们描述了如何基于一组反映环境结构特性的公理,结合视觉系统内部结构的假设,以原则性的方式推导出早期空间、空间-色和时空接受域的理想化功能模型,以保证在多个空间和时间尺度上对图像表示的一致处理。有趣的是,这一理论预测的视觉感受野形状与哺乳动物视网膜、LGN和初级视觉皮层(V1)测量的生物感受野在质量上非常相似。感受野;功能模型;高斯导数;规模协方差;仿射协方差;伽利略协方差;时间因果关系;光照不变性;视网膜;LGN;初级视觉皮层;简单的细胞;Double-opponent细胞;愿景
This article gives an overview of a normative theory of visual receptive fields. We describe how idealized functional models of early spatial, spatio-chromatic and spatio-temporal receptive fields can be derived in a principled way, based on a set of axioms that reflect structural properties of the environment in combination with assumptions about the internal structure of a vision system to guarantee consistent handling of image representations over multiple spatial and temporal scales. Interestingly, this theory leads to predictions about visual receptive field shapes with qualitatively very good similarities to biological receptive fields measured in the retina, the LGN and the primary visual cortex (V1) of mammals.
