Local and Global Feature Learning for Blind Quality Evaluation of Screen Content and Natural Scene Images

The blind quality evaluation of screen content images (SCIs) and natural scene images (NSIs) has become an important, yet very challenging issue. In this paper, we present an effective blind quality evaluation technique for SCIs and NSIs based on a dictionary of learned local and global quality feat...
