用量子信息理论重新定义颜色感知，更精准建模亮度等属性。
A quantum information-based refoundation of color perception concepts
- 引入量子效应与相对熵等概念重构颜色感知模型
- 严格推导出亮度恒常性现象，验证理论有效性
- 适合对视觉感知建模或量子认知感兴趣的读者
本文旨在通过数学严格的新定义，克服传统颜色感知属性的直观理解局限。基于近期发展的类量子颜色感知理论，该框架彻底颠覆了经典CIE模型及其颜色外观模型。我们展示量子信息中的效应、广义态、测量后变换及相对熵等概念，可完美用于建模亮度、明度、彩度、色度、饱和度和色调等属性。通过严谨推导，实现了对亮度恒常性现象的理论解释，充分验证了新定义的有效性。
原文摘要 · Abstract (English)
In this paper we deal with the problem of overcoming the intuitive definition of several color perception attributes by replacing them with novel mathematically rigorous ones. Our framework is a quantum-like color perception theory recently developed, which constitutes a radical change of view with respect to the classical CIE models and their color appearance counterparts. We show how quantum information concepts, as e.g. effects, generalized states, post-measurement transformations and relative entropy provide tools that seem to be perfectly fit to model color perception attributes as brightness, lightness, colorfulness, chroma, saturation and hue. An illustration of the efficiency of these novel definitions is provided by the rigorous derivation of the so-called lightness constancy phenomenon.
