To explore the feature and meaning of primary contrast sensitivity function (CSF) abnormal.
目的探讨原发性对比视觉功能异常的特点与意义。
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。
The comparison shows that the improved gray scale contrast function has simpler time computational complexity and higher focusing sensitivity.
实验对比表明，这种改进的灰度对比度函数，计算时间复杂度较简单，对焦灵敏度高。
