Human and machine visual sensing is enhanced when surface properties of objects in scenes, including color, can be reliably estimated despite changes in the ambient lighting conditions. We describe a computational method for estimating surface spectral reflectance when the spectral power distribution of the ambient light is not known.
当场景中物体的表面属性（包括颜色）能够在环境光照条件变化时得到可靠估计时，人类和机器的视觉感知就会得到增强。我们描述了一种在环境光的光谱功率分布未知时估计表面光谱反射率的计算方法。
