在本文中，我们提出了一种新的计算颜色恒常性模型，灵感来自人类视觉系统（HVS）的惊人能力，感知物体的颜色在很大程度上是恒定的光源颜色变化。该模型模拟了HVS第一阶段视网膜特定水平的颜色处理机制，从视锥细胞层和水平细胞层的适应到视网膜神经节细胞层的颜色对抗机制和非经典感受野的去抑制效应。特别地，HC调制提供了具有锥特定横向增益控制的全局颜色校正，并且随后的RGC利用迭代自适应来细化处理，直到所有三个对立通道达到它们的稳定状态（即，获得稳定的输出）。我们的模型不像大多数现有的算法那样显式地估计场景光源，而是直接去除场景光源的影响。四个常用的颜色恒常性数据集上的评价表明，该模型产生竞争力的结果相比，国家的最先进的方法，无论是单一或多个光源下的场景。结果表明，单重性，特别是RGCs感受野亚单位结构周围出现的去抑制效应，通过内在地区分表面的空间结构和广泛的光源，在去除场景光源中起着重要的作用。
In this paper, we propose a novel model for the computational color constancy, inspired by the amazing ability of the human vision system (HVS) to perceive the color of objects largely constant as the light source color changes. The proposed model imitates the color processing mechanisms in the specific level of the retina, the first stage of the HVS, from the adaptation emerging in the layers of cone photoreceptors and horizontal cells (HCs) to the color-opponent mechanism and disinhibition effect of the non-classical receptive field in the layer of retinal ganglion cells (RGCs). In particular, HC modulation provides a global color correction with cone-specific lateral gain control, and the following RGCs refine the processing with iterative adaptation until all the three opponent channels reach their stable states (i.e., obtain stable outputs). Instead of explicitly estimating the scene illuminant(s), such as most existing algorithms, our model directly removes the effect of scene illuminant. Evaluations on four commonly used color constancy data sets show that the proposed model produces competitive results in comparison with the state-of-the-art methods for the scenes under either single or multiple illuminants. The results indicate that single opponency, especially the disinhibitory effect emerging in the receptive field's subunit-structured surround of RGCs, plays an important role in removing scene illuminant(s) by inherently distinguishing the spatial structures of surfaces from extensive illuminant(s).
