| 摘 要： | 在传统的图像客观测试峰值信噪比的基础上，对比了重建图像与原始图像，改进了测试模糊及方块效应等关键质量指标的算法，同时提出了预处理的方案. 实用中可与图像质量主观评价的mean opinion score对应，并可用于测试与评价图像传输系统的质量.

| Abstract: | By contrasting the original video and the proceeded video, and on the base of peak-signal-to-noise ratio the traditional video quality measurement, we improve the algorithm of the critical merits such as blurring and blocking, and state the preprocess. Practice proved it can map with mean opinion score of subjective video quality evaluation. So the algorithm can apply for assessing and optimizing the code device. |

| Keywords: | objective video quality measurement peak-signal-to-noise ratio blurring blocking |
