Point cloud data compression
The rapid growth in the popularity of Augmented Reality (AR), Virtual Reality (VR), and Mixed Reality (MR) experiences have resulted in an exponential surge of three-dimensional data. Point clouds have emerged as a commonly employed representation for capturing and visualizing three-dimensional data in these environments. Consequently, there has been a substantial research effort dedicated to developing efficient compression algorithms for point cloud data. This Master's thesis aims to investigate the current state-of-the-art lossless point cloud geometry compression techniques, explore some of these techniques in more detail and then propose improvements and/or extensions to enhance them and provide directions for future work on this topic
CABAC accelerator architectures for video compression in future multimedida : a survey
The demands for high quality, real-time performance and multi-format video support in consumer multimedia products are ever increasing. In particular, the future multimedia systems require efficient video coding algorithms and corresponding adaptive high-performance computational platforms. The H.264/AVC video coding algorithms provide high enough compression efficiency to be utilized in these systems, and multimedia processors are able to provide the required adaptability, but the algorithms complexity demands for more efficient computing platforms. Heterogeneous (re-)configurable systems composed of multimedia processors and hardware accelerators constitute the main part of such platforms. In this paper, we survey the hardware accelerator architectures for Context-based Adaptive Binary Arithmetic Coding (CABAC) of Main and High profiles of H.264/AVC. The purpose of the survey is to deliver a critical insight in the proposed solutions, and this way facilitate further research on accelerator architectures, architecture development methods and supporting EDA tools. The architectures are analyzed, classified and compared based on the core hardware acceleration concepts, algorithmic characteristics, video resolution support and performance parameters, and some promising design directions are discussed. The comparative analysis shows that the parallel pipeline accelerator architecture seems to be the most promising
