The effect of any noise peak occurring during any one of the last 4 bit trials is therefore reduced.

因此发生在最后4个位试验中的任何一个期间的任一噪声峰的影响减小。

Experiment results show that in low bit rate environment, the new image compression scheme performs better than JPEG in the aspects of perception and PSNR (Peak Signal Noise Ratio).

实验结果表明该算法在低码率下，相比jpeg，获得了在视觉效果和峰值信噪比方面更好的恢复图像质量。

There are many kinds of image fusion methods, such as information entropy, mutual information, mean square error, peak signal to noise ratio and mean grads.

医学图像融合的效果评价方法有很多，如信息熵、 互信息、均方值、峰值信噪比和平均梯度等。

For example, spreading the same number of journeys over a greater period of time through trading across may well bring the benefits of easing congestion at peak times, but roadside residents will not be grateful when traffic noise and vibration start earlier in the morning and continue through the night.
