主观评价JPEG与JPEG2000标准的彩色图像最佳压缩比的实验研究
DOI: 10.11834/jig.20100702
Keywords: 主观评价,图像压缩,最佳压缩比,JPEG,JPEG2000
Abstract:
研究压缩图像在显示器上质量主观评价方法，为实现Internet上图像质量主观评价奠定基础。研究包括显示器设置问题；在彩色电视图像质量主观评价ITU-BT？500-11标准的基础上，提出静态压缩图像评价指标；收集了标准彩色测试图像并建立图像库。最后使用JPEG与JPEG2000两种压缩标准对具有不同性质的20景彩色图像进行了7种压缩比的有损压缩，并选取10人采用成对比较的视觉心理物理学方法，对压缩图像进行主观评价实验。得出了JPEG标准下彩色图像最佳压缩比范围为20：1~25：1，JPEG2000范围为25：1~30：1，同时实验结果表明，可以通过视觉的方法对不同LCD显示器进行设置，并达到一个大致相同的设置效果。
