CMMB图像质量主观评价方法研究

摘要

In this paper, the relevant standards in video image quality measurements at home and abroad are analyzed at first. After that, combined with China Mobile Multimedia Broadcasting (CMMB) system characteristics, the subjective measurement methods is analyzed deeply, and main issues during the process of CMMB image quality measurement are discussed. Based on above analysis, a subjective measurement system of image quality on CMMB is designed and implemented, and the experimental results prove the reliability of this measurement system.%通过分析目前国内外视频图像质量评价的相关标准,并结合中国移动多媒体广播(CMMB)系统的应用特性,对图像质量主观评价方法进行深入分析,提出了在进行CMMB图像质量主观评价过程中需要考虑的主要问题.在此基础上,进一步设计并实现对CMMB图像质量的主观评价,并对评价结果进行了统计分析,以验证评价方法的可靠性.
