论文摘要
以前，已经开发了一种方法来找到给定相机的最佳颜色滤波器，从而导致新的有效相机敏感性最能满足路德条件。也就是说，新的敏感性与XYZ颜色匹配函数大致相关。但是，在没有约束的情况下，从这个基于路德条件的优化中得出的过滤器可能是非平滑的，并且很少传输光线，这对于制造而言是不切实际的。 在本文中，我们扩展了路德条件滤波器优化方法，使我们能够合并回收过滤器的平滑度和透射率，这是关键实际问题。实验表明，我们可以找到可实现的过滤器，这些过滤器是平滑且经常传播的，有效的“相机+滤镜”变得更加比色。
Previously, a method has been developed to find the best colour filter for a given camera which results in the new effective camera sensitivities that best meet the Luther condition. That is, the new sensitivities are approximately linearly related to the XYZ colour matching functions. However, with no constraint, the filter derived from this Luther-condition based optimisation can be rather non-smooth and transmit very little light which are impractical for fabrication. In this paper, we extend the Luther-condition filter optimisation method to allow us to incorporate both the smoothness and transmittance bounds of the recovered filter which are key practical concerns. Experiments demonstrate that we can find physically realisable filters which are smooth and reasonably transmissive with which the effective "camera+filter" becomes significantly more colorimetric.
