简介：我们为基于波前错误和isoluminant颜色对比敏感功能(CSF)的大小决定孤立的颜色机制的神经对比敏感功能(NCSF)建议一个新方法。与传统的方法相比，这种技术避免协调噪音和点缀噪音，它被激光横梁的干扰带，并且为不同颜色机制的NCSF的大小有大灵活性。当蓝机制的那些是最低的时，我们的实验显示分别地，红机制的吝啬的NCSF和CSF比绿机制的那些高。然而，在红、绿的机制之间的NCSF和CSF的山峰的相对高度在题目变化。有一些个人，NCSF的价值或绿机制的CSF其山峰比红机制的高。孤立的颜色机制的NCSF和CSF都展出类似的特征和变化趋势。与统计一般水准，红、绿、蓝的机制的NCSF比在整个空间频率的相应CSF高。与相应CSF曲线相比，孤立的颜色机制的NCSF的山峰向更高空间的频率变，特别为有3.9c/deg的最大的移动的蓝机制的。[从作者抽象]
