摘要
本文提出了一种基于多维直方图的灰度数字图像质量评价指标—信息容量.该指标引入了图像相关性和视觉响应特性,这种评价具有客观、易计算和与视觉一致的特点.文中给出了关于信息容量的理论分析和实验评定结果.
Information content is proposed in this paper to measure quality of images based on image multidimensional histogram. It takes account of image local correlation, global cumulation, and human vision. So it's objective and consistent with human subjective evaluation.
