| 摘 要： | K系数指标是评价电视信号质量优劣的重要指标之一 ,是在把各种波形失真按人眼视觉特性给以不同评价的基础上来度量图像损伤的一套系统的方法 ,它由K50 ,Kb,Kpb,Kp 等指标组成 ,在图像上分别反映了垂直方向上的亮度不均匀 ,水平方向上的亮度变化 ,以及图像的细节、边缘、轮廓等的失真。

| Abstract: | K coefficient is one of the important indexes judging whether the TV signals are good or not, and it is also a means to measure the scathing images according to different evaluations of wave distortions from human viewing angles. It consists of such indexes as K_ 50,K_b,K_ pb,K_p and so on, which can reflect in image asymmetry luminance, light variety and different kinds of distortion. |
