Textbook trichromacy accounts for human color vision in terms of spectral sampling by three classes of cone photoreceptors. This account neglects entangling of color and pattern information created by wavelength-dependent optical blur (chromatic aberrations) and interleaved spatial sampling of the retinal image by the three classes of cones. Recent experimental, computational, and neurophysiological work is now considering color and pattern vision at the elementary scale of daylight vison, that is at the scale of individual cones. The results provide insight about rich interactions between color and pattern vision as well as the role of the statistical structure of natural scenes in shaping visual processing.
教科书式的三色视觉理论是根据三类视锥光感受器的光谱采样来解释人类的色觉。该理论忽略了由波长依赖性光学模糊(色差)产生的颜色和图案信息的纠缠,以及三类视锥细胞对视网膜图像的交错空间采样。最近的实验、计算和神经生理学研究正在从日光视觉的基本尺度,即单个视锥细胞的尺度,来考虑颜色和图案视觉。这些结果为颜色和图案视觉之间的丰富相互作用,以及自然场景的统计结构在塑造视觉处理过程中的作用提供了见解。
