Hybrid 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 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 کاملModulus quantization for matching-pursuit video coding
Overcomplete signal decomposition using matching pursuits has been shown to be an eecient technique for coding motion residual images in a hybrid video coder. Unlike orthogonal decomposition, matching pursuit uses an in-the-loop modulus quantizer which must be speciied before coding begins. This complicates the quantizer design, since the optimal quantizer depends on the statistics of the match...
متن کاملDictionary Approximation for Matching Pursuit Video Coding
Previously, we demonstrated an efficient video codec based on overcomplete signal decomposition using matching pursuits. Dictionary design is an important issue for this system, and others have shown alternate dictionaries which lead to either coding efficiency improvements or reduced encoder complexity. In this work, we introduce for the first time a design methodology which incorporates both ...
متن کاملFractal video coding by matching pursuit
Fractal image and video coders use redundancies present in different scales of natural images for compression. Motion compensation, on the other hand, is a powerful method for exploiting similarities at the same scale in frames of a video sequence. In this paper, a new method is proposed to take advantage of both interscale and intrascale selfsimilarities present in video sequences. A rate-dist...
