Estimating QP and motion vectors in H.264/AVC video from decoded pixels
Giuseppe Valenzise, Marco Tagliasacchi, Stefano Tubaro · 2010
In this paper we present a method for blindly estimating the quantization parameter (QP) and the motion-vectors in H.264/AVC decoded video. We assume that only the decoded pixel values are available. This models pretty well the dissemination over the Internet of user-generated contents, where a video may pass through several coding/processing stages from acquisition to publication and download.
