摘要:

提出了一种基于自然图像统计模型的简化参考图像质量测度。为此,Tetrolet变换被使用,因为它提供了一种方便的方式来捕获局部几何结构。该变换应用于参考图像和失真图像。然后,高斯尺度混合(GSM)提出了模型的子带,以考虑统计之间的依赖关系的tetrolet系数。为了量化视觉退化,提供了基于Kullback Leibler散度(KLD)的度量。在Cornell VCL A-57数据集上测试了所提出的措施,并根据FR-TV 1 VQEG框架与其他措施进行了比较。

英文摘要:

This paper deals with a reduced reference (RR) image quality measure based on natural image statistics modeling. For this purpose, Tetrolet transform is used since it provides a convenient way to capture local geometric structures. This transform is applied to both reference and distorted images. Then, Gaussian Scale Mixture (GSM) is proposed to model subbands in order to take account statistical dependencies between tetrolet coefficients. In order to quantify the visual degradation, a measure based on Kullback Leibler Divergence (KLD) is provided. The proposed measure was tested on the Cornell VCL A-57 dataset and compared with other measures according to FR-TV1 VQEG framework.
