| 摘 要： | 本文论述了图象质量的各种定量测度,包括连续的和离散的形式。着重讨论了基于视觉特性的图象质量测度,它们与主观评价具有很好的相关性;提出了用图象信息量作图象质量测度的方法。这些测度在图象压缩、图文传真中具有重要的应用。图象质量的测度是对图象质量的评价,它对复原算法优劣的评价是一个十分重要的依据。

| Abstract: | A variety of quantitative measures of the image quality,including the continuous and discrete forms,is investigated.Most emphases are placed on the measures of the image quality based on the visual system models,which have better correlation with the subjective evaluation.The image information is proposed as a new measure of the image quality.These measures have wide applications in the image compression and facimile.The measure of the image quality evaluates the imag quality is a very important criterion for the evaluation of the image restoration algorithms. |
