In rate-distortion optimization, the encoder settings are determined by maximizing a
reconstruction quality measure subject to a constraint on the bitrate. One of the main …

In this paper, we investigate the impact of spatial, temporal, and amplitude resolution on the
perceptual quality of a compressed video. Subjective quality tests were carried out on a …

Multi-dimensional rate control schemes have been recently utilized to adapt video streams
to dynamic network conditions and heterogeneous devices. However, current multi …

In this paper, we investigate the impact of spatial, temporal and amplitude resolution (STAR)
on the perceptual quality of a compressed video. Subjective quality tests were carried out on …

In this paper, we investigate the impacts of spatial, temporal and amplitude resolution
(STAR) on the bit rate of a compressed video. We propose a rate model in terms of the …

Current rate control systems use the frame complexity to determine the frame-level bitrates.
These methods ignore the dependence between the current frame and its reference frames …

In networked video applications where the sustainable bandwidths vary greatly among the
receivers and in time, one must be able to code a video or adapt a precoded-bitstream to a …

Scalable video is an efficient and effective solution to stream video over heterogeneous
networks to different clients, where a full resolution video bit stream can be adapted or …
