立体图像质量的主观评价方案

Subjective Quality Evaluation Method of Stereo Image

立体图像质量评价在立体图像压缩、处理以及通信领域中有着十分重要的作用,一种好的立体图像质量客观评价方法也要依赖于立体图像的主观评价.本文基于人眼的立体视觉特性,提出了相对完整的立体图像质量主观评价方案,该方案主要分为立体图像库的建立、评测者的选择、观看条件的描述、评测者的训练和测试、数据处理和实验结果分析六个方面.实验中,评测者根据自己的主观感受,对所选取的立体图像进行评分,最后用数理统计理论对所得数据进行处理.结果表明,本文所提出的主观评价方案可行,能够正确反映立体图像质量的优劣.

Quality evaluation method of stereo image plays an important role in image compression,processing and communications,and objective quality evaluation method of stereo imagedepends on the subjective evaluation.Based on the characteristics of the human eye stereo vision,a new subjective evaluation is proposed.In this paper,six aspects in details are described: building stereo image library,the choice of evaluators,description of experimentcondition,training and testing evaluators,dataprocessing and analysis of experiment result.The experiments results are the scores of stereo image,which can be assessed by different evaluators and processed by the theory of mathematical statistics.The resultsuggests that subjective quality evaluation method isreasonable and can state stereo image quality accurately.
