In general, the ideal IQA metric should be effective and efficient, yet most of existing FR IQA methods cannot reach these two targets simultaneously. Under the supposition that the human visual perception to image quality depends on salient local distortion and global quality degradation, we introduce a novel...
In the study of image quality assessment (IQA), multi-scale methods are often used because they can supply more flexibility than single-scale ones by incorporating the variations of viewing conditions. However, some recent work demonstrated that single-scale methods based on scale transformation also performed well in terms of the correlation between the quality predictions and the subjective scores...
