Abstract
In recent years, the research of the no-reference (NR) image quality assessment (IQA) has been very active. But the NR-IQA research for noise-distorted images hasn't been proposed yet. In this paper, we propose a NR-IQA metric for noise-distorted images based on bidimensional empirical mode decomposition (BEMD) and Riesz transform, namely BRIQ index. Firstly, the denoised image is obtained by using the BEMD, Riesz transform and the visual contrast sensitivity function (CSF) to denoise the distorted image. Then the similarity calculation is performed using five Riesz transform feature maps of the distorted image and the denoised image. Finally, we combine these five similarity indices to obtain the final quality score for the distorted image. Experimental results on pubic database show that the BRIQ index evaluates the noise-distorted images with good performance, as consistent as subjective quality ratings.
