人类擅长从投射在视网膜上的2D图像中推断出关于3D场景的信息，使用广泛的深度线索。这种推断的一个例子是观察者倾向于将较亮的图像区域感知为较近。这种心理物理行为可能具有生态学基础，因为在自然3D场景中，较近的区域往往较亮。在这里，我们表明，一个类似的关联存在于猕猴初级视觉皮层的神经元的相对亮度和双眼视差偏好之间。在神经元群体水平上的相对亮度和双眼视差的联合编码可能是用于从图像感知深度的神经机制的组成部分。
Humans excel at inferring information about 3D scenes from their 2D images projected on the retinas, using a wide range of depth cues. One example of such inference is the tendency for observers to perceive lighter image regions as closer. This psychophysical behavior could have an ecological basis because nearer regions tend to be lighter in natural 3D scenes. Here, we show that an analogous association exists between the relative luminance and binocular disparity preferences of neurons in macaque primary visual cortex. The joint coding of relative luminance and binocular disparity at the neuronal population level may be an integral part of the neural mechanisms for perceptual inference of depth from images.
