Data Compression and Harmonic Analysis
In this article we review some recent interactions between harmonic analysis and data compression. The story goes back of course to Shannon’s R(D) theory in the case of Gaussian...

Towards jointly optimal spatial prediction and adaptive transform in video/image coding
This paper proposes a new approach to combined spatial (Intra) prediction and adaptive transform coding in block-based video and image compression. Context-adaptive spatial predic...

Quantization of Overcomplete Expansions
The use of overcomplete sets of vectors (redundant bases or frames) together with quantization is explored as an alternative to transform coding for signal compression. The goal i...

A New Image Coding Technique Unifying Fractal and Transform Coding
We present a new image coding scheme based on an unification of fractal and transform coding. We introduce a generalization of the luminance transformation used by fractal coding ...

Optimal Multiple Description Transform Coding of Gaussian Vectors
Multiple description coding (MDC) is source coding for multiple channels such that a decoder which receives an arbitrary subset of the channels may produce a useful reconstruction...

Wavelet-Based Video Compression Using Long-Term Memory Motion-Compensated Prediction and Context-Based Adaptive Arithmetic Codin
In this paper, we present a novel design of a wavelet-based video coding algorithm within a conventional hybrid framework of temporal motion-compensated prediction and transform co...

Permutation-Based Low-Complexity Alternate Coding in Multi-View H.264/AVC
1 Low bitrates enabled by the H.264/AVC standard come at the cost of significant decoding complexity. The problem is exacerbated when multi-view video coding (MVC), presently being...

Design of Optimal Decimation and Interpolation Filters for Low Bit-Rate Image Coding
— The DCT-based JPEG standard is certainly one of the most successful applications of transform coding methods for still digital images. A commonly recognized disadvantage of the...

Video Coding Using Spatially Varying Transform
In this paper, we propose a novel algorithm, named as Spatially Varying Transform (SVT). The basic idea of SVT is that we do not restrict the transform coding inside normal block b...
