环境中日光的微小变化即使在短时间内也会产生反射光的巨大变化。这些变化是否限制了表面颜色的视觉识别？为了解决这个问题，信息理论的方法被用来估计计算的最大数量的表面在一个样本中，可以被识别为相同的间隔后。场景数据取自连续的高光谱辐射图像。在没有照明变化的情况下，通过颜色可区分的表面的平均数量为10，000。但随着光照的变化，平均可辨认数量随着变化时间的延长而迅速下降。在一种情况下，两分钟后的数字约为600，10分钟后约为200，一小时后约为70。这些识别的限制比日光下的光谱变化要低得多。没有重新编码的颜色信号是可能恢复在这种不确定的环境中丢失的表面身份。
Small changes in daylight in the environment can produce large changes in reflected light, even over short intervals of time. Do these changes limit the visual recognition of surfaces by their colour? To address this question, information-theoretic methods were used to estimate computationally the maximum number of surfaces in a sample that can be identified as the same after an interval. Scene data were taken from successive hyperspectral radiance images. With no illumination change, the average number of surfaces distinguishable by colour was of the order of 10,000. But with an illumination change, the average number still identifiable declined rapidly with change duration. In one condition, the number after two minutes was around 600, after 10 min around 200, and after an hour around 70. These limits on identification are much lower than with spectral changes in daylight. No recoding of the colour signal is likely to recover surface identity lost in this uncertain environment.
