No-reference video quality assessment in the compressed domain

IEEE Transactions on Consumer Electronics, 2012
In this paper, a novel no-reference video quality assessment algorithm in the compressed domain is introduced. The proposed algorithm takes into account of three key factors; the quantization parameter, the motion, and the bit allocation factor which are calculated using the information extracted from the compressed bitstream.

CVD2014—A Database for Evaluating No-Reference Video Quality Assessment Algorithms

IEEE Transactions on Image Processing, 2016
In this paper, we present a new video database: CVD2014-Camera Video Database. In contrast to previous video databases, this database uses real cameras rather than introducing distortions via post-processing, which results in a complex distortion space in regard to the video acquisition process.
