As filter Banks are used to simulate the contrast sensitivity function (CSF) in these models, the complexity of visual threshold obtainment and real-time (assessment) algorithms are increased.

由于这些模型采用滤波器组模拟对比度敏感函数(CSF)，增加了视觉阈值获取和实时评价算法的复杂度。

Both of the contrast vision and contrast threshold possess double function information of vision and contrast sensitivity, but a few functions of some eye diseases failed to respond in the same way.

对比视力和对比阈值都具有视力和对比敏感性的双功能信息，但在部分病眼功能的反映上不尽相同。
