We have described a number of transformations by mapping the cone signal vector , formed by , to opponent space , formed by achromatic signal , red-green signal and yellow-blue signal . Two new transformations, and , are proposed, based on the CIE 2006 spectral luminous efficiency function, , and Hurvich's opponent spectral red-green and yellow-blue responses, and , without and with constraints, respectively. is better than in terms of best fit of and , and both transformations improved previously proposed ones. Finally, we discuss the neutral conditions in cone space using each of the new and some of the extant transformations, as well as choosing scaling factors so that the neutral conditions in cone space are satisfied.

从锥体响应到对手颜色空间的转换

我们通过将由 形成的锥体信号向量映射到由消色差信号、红绿信号和黄蓝信号形成的对手空间来描述了许多变换。基于 CIE 2006 光谱发光效率函数和 Hurvich 的对手光谱红绿和黄蓝响应，和，分别提出了两个新的变换，和，没有约束和有约束。优于和 的最佳拟合，并且两种变换都改进了先前提出的变换。最后，我们讨论中性条件在锥空间中使用每个新的和一些现存的变换，以及选择比例因子以满足锥空间中的中性条件。
