通过与标准RVLC方法比较可得,IRVLC方法得到了较好的解码质量,平均峰值信噪比(Peak s igna l-no ise rate,PSNR)提高了1~2 dB,证明了IRVLC方法的有效性,且与M PEG-4标准完全兼容。

实验结果证明，该算法不仅能显著提高平均峰值信噪比，并能大幅减少跳帧数目。
Experimental results show that, the proposed algorithm can improve the average PSNR and decrease the number of skipped frames significantly.
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。
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.
显见，动态阈是用准峰值电平表示，而信噪比则是用准平均值电平表示的，两者的区别是显而易见的了。
Obviously, the dynamic threshold is to use quasi-peak level that, while the signal to noise ratio is expressed with the quasi-average levels, and the difference is obvious in.
