Rate Control for Layered Video Compression Using Matching Pursuits
The use of matching pursuits (MP) to compress motion compensated residual video signals and its extension to layered coding have recently been demonstrated in [1, 2]. In this paper we describe a multi-pass rate control scheme for SNR scalable encoding based on MP. The rate control algorithm enforces constant quality on each layer, while keeping the bit budget for each layer at a pre-specified t...
متن کاملVideo Compression Using Matching Pursuits - Circuits and Systems for Video Technology, IEEE Transactions on
The use of matching pursuit (MP) to code video using overcomplete Gabor basis functions has recently been introduced. In this paper, we propose new functionalities such as SNR scalability and arbitrary shape coding for video coding based on matching pursuit. We improve the performance of the baseline algorithm presented earlier by proposing a new search and a new position coding technique. The ...

متن کاملRobust and scalable video compression using matching pursuits and absolute value coding
The main objective of this paper is to develop a fine grained scalable video codec which can fully exploit temporal correlation’s within all layers, and thus offer performance closer to that of a single layer non-scalable system. To this end we propose the use of a combination of matching pursuits together with absolute value coding of the displaced frame difference information. The proposed co...
متن کاملVery low bit rate video coding using matching pursuits
The term matching pursuits refers to a greedy algorithm which matches signal structures to a large, diverse dictionary of functions. The technique was proposed by Mallat and Zhang 1 with an application to signal analysis. In this paper, we show how matching pursuits can be used to e ectively code the motion residual in a hybrid video coding system at bit rates below 20 kbit/s. One advantage of ...
