基于Contourlet变换的质降参考图像质量评价模型

Contourlet-based reduced-reference image quality assessment model

提出了一种新的基于Contourlet变换的质降参考图像质量评价模型(RR-CTBM),通过衡量图像间的纹理相似度,达到质量度量的目的。实验结果表明,所提出的RR-CTBM与主观视觉感知具有较好的一致性。

An objective reduced-reference image quality evaluation metric based on contourlet transform （RR-CTBM） is proposed.The metric measures the quality of distortion image by computing the texture similarity between the features which are extracted from reference and distorted images,respectively.Experiments demostrate that the novel objective metric achieves consistent image quality evaluation results with that gained by subjective evaluation.
