颜色转移算法的目的是将调色板，情绪或风格从一个图像应用到另一个图像，在三维颜色空间中操作，或者将问题分成三个更简单的一维问题。后一类算法简单地独立地处理三个维度中的每一个，无论是否合理。虽然它们很少引入空间伪影，但结果的质量取决于如何将问题分成三个子问题，即选择哪个颜色空间。通常，假设去相关的颜色空间将表现最好，因为去相关使得三个颜色通道半独立（去相关是比独立更弱的属性）。然而，这样的空间仅针对精心选择的图像集合去相关。对于单个图像，此属性可能不成立。在这项工作中，彩色图像的自然统计和现有的颜色转移算法产生合理的结果的能力之间的连接进行了研究。这项工作的目的是提供一个更好的理解不同的颜色空间的颜色转移的情况下的性能。
Colour transfer algorithms aim to apply a colour palette, mood or style from one image to another, operating either in a three-dimensional colour space, or splitting the problem into three simpler one-dimensional problems. The latter class of algorithms simply treats each of the three dimensions independently, whether justified or not. Although they rarely introduce spatial artefacts, the quality of the results depends on how the problem was split into three sub-problems, i.e. which colour space was chosen. Generally, the assumption is made that a decorrelated colour space would perform best, as decorrelation makes the three colour channels semi-independent (decorrelation is a weaker property than independence). However, such spaces are only decorrelated for well-chosen image ensembles. For individual images, this property may not hold. In this work, the connection between the natural statistics of colour images and the ability of existing colour transfer algorithms to produce plausible results is investigated. This work aims to provide a better understanding of the performance of different colour spaces in the context of colour transfer.
