彩色视觉中恢复饱和度信息的探讨

Discussion of Recovering Saturation in Colour Vision

在本文中，我们对物体饱和度信息的变化做了分析，对以前的一些获取颜色恒常性的方法做了比较，指出它们一般都不能得到恒常性的饱和度信息。我们认为，人类视觉对饱和度的分析，也具有孔径效应，在失去形状信息时，对饱和度的确定也会产生困难。因此在彩色视觉研究中，只有借助定性的形状信息，才能得到有意义的饱和度信息。

In this paper,we analyze the variation of saturation,also we compare the previous methods of color constancy and point out that they can not get the constant saturation information.We assume that human vision has aperture effect in saturation analysis.Namely,human being will come into difficulty in determining saturation information without shape information.Hence,shape analysis and color analysis should be combined together.
