摘要
迄今为止 ,压缩重构图象的质量评价还没有统一的标准。通常使用的峰 -峰信噪比或均方误差与主观感觉并不相符 ,而主观评价又存在主观性和不确定性 ,其结果往往因人而异。笔者根据人眼视觉特征研究了具有视觉心理特点的压缩重构图象质量的评价指标体系 ,提出了Ce、De、Be评价指标 ,较好地表述了重构图象的质量 ,且容易理解。
There is no unified standard for the quality assessment of reconstruction image up to now.The Results by using Pick-pick Signal Noise Ratio(PSNR)or mean square error(mse)are different from by subjective psychological assessment, while the latter are usually inexactly and have subjectivity.The index system for quality assessment of reconstructed image based on psychology of human vision is researched , and the assessment indexes Ce、De、Be are presented.Such indexes can express the status of reconstructed image truly.
