Paper Abstract

No reference (NR) method is the most difficult issue of image quality assessment (IQA), which does not need the original image or its features as reference and only depends on the statistical law of the natural images. So, the NR-IQA is a high -level evaluation for image quality and simulates the complicated subjective process of human beings. This paper presents a NR-IQA metric based on Hidden Markov Tree (HMT) model. First, the HMT is utilized to model natural images, and the statistical properties of the model parameters are analyzed to mimic variation of image degradation. Then, by estimating the deviation degree of the parameters from the statistical law the distortion metric is constructed. Experimental results show that the proposed image quality assessment model is consistent well with the subjective evaluation results, and outperforms the existing models on difference distortions.
