Blind blockiness measure based on marginal distribution of wavelet coefficient and saliency

摘要: The objective measurement of blockiness plays an important role in many applications, such as the quality assessment image, and design image video coding system. However, most existing no-reference metrics do not consider influences grid distortion on performance metric. In this paper, we propose a new metric, which is robust to distortion, based marginal distribution local wavelet coefficients saliency information. Experiments for several public databases showed that proposed metric provides consistent correlations with subjective scores outperforms other metrics.
