Rate control (RC) is crucial in controlling compression bit rates and qualities for networked video applications.
In this paper, we propose a new rate-distortion (R-D) model and an efficient rate control scheme for H.264/AVC video coding, which[...]

In this paper, we propose a novel two-pass rate control algorithm to achieve constant quality for H.264/AVC high definition video coding.
With the first-pass collected rate and distortion information and the built model of scene complexity, the[...]

The problem of enabling robust video transmission over lossy networks has become increasingly important because of the growing interest in video delivery over unreliable channels such as wireless networks.
The more the coding process relies on [...]

This paper presents a unified approach for low-memory and on-the-fly implementation of generic hierarchical transforms (GHTs) suited for parent–children tree (PCT) production, called the stripe-based hierarchical transform (SBHT).
Here, the ter[...]

High dynamic range (HDR) image requires a higher number of bits per color channel than traditional images.
This brings about problems to storage and transmission.
Color space quantization has been extensively studied to achieve bit encodings f[...]

The new video coding standard, H.264 uses variable size motion estimation (VS-ME), multiple reference frame motion estimation (MRF-ME) and spatial-based intra prediction with selectable block size in inter frame coding.
These tools have achieve[...]
