In this work, we propose a novel rate control algorithm for Versatile Video Coding (VVC) standard based on its distinct rate-distortion characteristics. By modelling the transform coefficients with composite Cauchy distribution, higher accuracy compared traditional distributions has been achieved. Based coefficient modelling, theoretically derived R-Q and D-Q models which have shown to deliver ...

The latest HEVC video coding standard [1] has improved the coding performance by applying a number of innovative tools compared to its predecessor H.264/AVC [2][3] including a wider range of variable block size motion estimation (ME), motion compensation (MC), prediction, and transformation units. The use of multiple reference frames (MRFs) with variable block sizes typically provides better co...

Wireless visual sensor networks are potentially applicable for several emerging applications. Since the data size of the video captured from multiple sensors increases in proportion to the number of video sensors, the efficient compression of video data from multiple sensors is important and still challenging. However, most current multiview video coding approaches extended from single-view vid...

A unified architecture for fast and efficient computation of the set of two-dimensional (2-D) transforms adopted by the most recent state-of-the-art digital video standards is presented in this paper. Contrasting to other designs with similar functionality, the presented architecture is supported on a scalable, modular and completely configurable processing structure. This flexible structure no...
