基于 Riesz 变换的结构相似度图像质量评价方法
Image quality assessment method via Riesz-transform based structural similarity
摘要
Abstract
Various distortions will be introduced to images during different image processing proce-dures,and the assessment of image quality has become a hot topic.According to the fact that the tra-ditional pixel-difference statistics-based PSNR method and structural similarity method cannot corre-late well with human subjective evaluation,a novel image quality assessment method via Riesz-Trans-form based structural similarity is proposed.The method firstly applies 1st-order Riesz-Transform and 2nd-order Riesz Transform to the reference image and distorted image,and 5 groups of corre-sponding features maps are obtained to produce 5 similarity maps and 5 weighting maps.Then the average-method fusion is performed to get the final similarity map and weighting map.Lastly,the lu-minance comparison of the original reference image and distorted image is considered to get the final image quality index.The experiments on the LIVE database indicate that the proposed method has high prediction accuracy and consistency on all 5 distortion types.It also outperforms the SSIM method under cross-distortion conditions and the PLCC value and SROCC value reach 0.948 2 and 0.953 2 respectively.Compared with other state-of-the-art methods,the proposed method owns good predictive performance,which indicates better consistency with human subjective perception.关键词
