| 摘 要： | 基于LCD运动图像锐度的视觉感知实验,采用线性回归的方法,得到人眼感知到的运动图像边缘锐度参量Zscore的计算表达式,提出了利用与边界斜率和过驱动相关的2个参数来描述运动图像边缘模糊程度的量化公式.并将计算预测值和视觉感知的实验值进行比较.结果表明,二者具有较高的相关性(R2≥0.8892),该量化公式可以很好地用于...

| Abstract: | A new calculation method and expression for the perceived sharpness metric in LCDs(liquid crystal displays) is proposed.Based on visual perception experiment,two new evaluation parameters Cslope and OD(over-drive),related to the edge slope and over/under-shoot part of luminance edge profile respectively,are put forward to predict the perceived sharpness.Experiments are conducted to verify the feasibility and effectiveness of this predicted perceived sharpness formula.The results show a high correlation betw... |
