基于边缘的SSIM图像质量客观评价方法
Objective Evaluation Method for Image Quality Based on Edge Structure Similarity
摘要
在图像处理领域中,准确判断所处理图像的质量是一项关键技术.本文在基于结构相似度的图像质量评价方法的基础上,考虑了边缘信息对人眼感知结构的重要性,提出了基于边缘结构相似度的图像质量评价方法.实验中,对实验图像进行客观指标的提取与计算,最后统计分析实验数据.结果表明,该方法对图像质量的评价结果优于基于结构相似度的图像质量评价方法,能够正确反映图像质量且更加符合人眼的主观感受.
Abstract
In the image-processing area, accurate evaluation of the processed quality is a key technique. In this paper, a new method using image edge combined with structural similariy,whichtakes the importanceof the edge information to eye perception structure into account, is presented. The objective indexes of experimental images are extracted and calculated, and the experimental data are statistical analysed.The results show that, the new method is better than the structural similarity image quality assessment method and is better fit with the subjective feeling of human visual perception.
