Atom Position Coding in a Matching Pursuit Based Video Coder
In this paper, we propose a new scheme for position coding of the atoms within the Matching Pursuit algorithm as applied to the displaced frame difference (DFD) in a hybrid video encoder. We exploit the spatial and temporal coherence of the positions of the atoms in the DFD: the atoms tend to cluster in regions where the motion prediction fails. The location of these regions is correlated over ...
متن کاملPerformance and Quality Issues in Matching Pursuit Residue Coding
Usually a block-based DCT transform is used in hybrid video coding to decompose motion compensated residuals. Another method, which has been successfully applied to the coding of video residuals, is Matching Pursuit (MP). Matching Pursuit is an overcomplete expansion technique providing some advantages over orthogonal transforms like DCT. In this paper we discuss the coding efficiency of a MP c...
متن کاملHybrid video coding using bi-dimensional matching pursuit
In this report we propose a new coding scheme based on the Matching Pursuit algorithm and exploiting some of the new features introduced by H.264 for motion estimation. Main points of this work are the design of a redundant dictionary suitable for coding displaced frame differences, the use of fast techniques for atom selection, which work in the Fourier domain and exploit the spatial localizat...
متن کاملHybrid Video Coding Based on Bidimensional Matching Pursuit
Hybrid video coding combines together two stages: first, motion estimation and compensation predict each frame from the neighboring frames, then the prediction error is coded, reducing the correlation in the spatial domain. In this work, we focus on the latter stage, presenting a scheme that profits from some of the features introduced by the standard H.264/AVC for motion estimation and replace...
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 ...
