Reduced Frame Quantization in Video Coding
We vary the quantization parameter in H.264 video encoding by increasing it by a well-chosen offset in every other frame, which we call reduced frames. As the motion compensation ...

Perceptual Quality Assessment of Video Considering Both Frame Rate and Quantization Artifacts
In this paper, we explore the impact of frame rate and quantization on perceptual quality of a video. We propose to use the product of a spatial quality factor that assesses the q...

Real-Time Very Low Bit Rate Video Coding with Adaptive Mean-Removed Vector Quantization
This is a contribution for very low bit rate video coding in real-time and software only on computers of PC class. It is based on frame replenishment with block coding using mean-...

Dependent bit allocation in multiview video coding
We consider the bit allocation problem in multiview video coding (MVC). A dependent coding technique using trellis expansion and the Viterbi algorithm (VA) is proposed, which take...

A New Quantization for Rate Control with Frame Variation Consideration
— The main role of rate control in video coding is to handle a trade-off between a bandwidth limit and a video quality. In the low-delay video communication systems, its responsi...
