我们在配对论文中对颜色不变性的分析[J.opt.SoC。Am A 10,2148(1993)]提供了一种算法，使人们可以测试线性颜色恒定方案的工作情况。在这里，我们给出了将该算法应用于一大类涉及双线性模型的颜色恒定问题的结果，该双线性模型将光感受器光谱灵敏度、表面反射函数和光源光谱功率分布联系起来。这些结果在模拟和进一步分析的支持下，提供了用于从反射光中恢复反射率和光源的光谱特性的两阶段线性方法的详细分类。
Our analysis of color constancy in a companion paper [J. Opt. Soc. Am A 10, 2148 (1993)] provided an algorithm that lets one test how well linear color constancy schemes work. Here we present the results of applying the algorithm to a large parametric class of color constancy problems involving bilinear models that relate photoreceptoral spectral sensitivities, surface reflectance functions, and illuminant spectral power distributions. These results, supported by simulation and further analysis, provide a detailed classification of two-stage linear methods for recovering the spectral properties of reflectances and illuminants from reflected lights.
