Polar Codes are Optimal for Lossy Source Coding

We consider lossy source compression of a binary symmetric source with Hamming distortion function. We show that polar codes combined with a low-complexity successive cancellation encoding algorithm achieve the rate-distortion bound. The complexity of both ...

Image interpolation with edge-preserving differential motion refinement

Thomas Maugey

Motion estimation (ME) methods based on differential techniques provide useful information for video analysis, and moreover it is relatively easy to embed into them regularity constraints en- forcing for example, contour preservation. On the other hand, th ...

MDCT for Encoding Residual Signals in Frequency Domain Linear Prediction

Petr Motlicek, Hynek Hermansky, Sriram Ganapathy

Frequency domain linear prediction (FDLP) uses autoregressive models to represent Hilbert envelopes of relatively long segments of speech/audio signals. Although the basic FDLP audio codec achieves good quality of the reconstructed signal at high bit-rates ...

An Information Theoretic Approach to Speaker Diarization of Meeting Data

Hervé Bourlard, Fabio Valente, Deepu Vijayasenan

A speaker diarization system based on an information theoretic framework is described. The problem is formulated according to the Information Bottleneck (IB) principle. Unlike other approaches where the distance between speaker segments is arbitrarily intr ...

Localization through Surface Folding in Solid Foams under Compression

Pedro Miguel Nunes Pereira de Almeida Reis

We report a combined experimental and theoretical study of the compression of a solid foam coated with a thin elastic film. Past a critical compression threshold, a pattern of localized folds emerges with a characteristic size that is imposed by an instabi ...

An Asynchronous Programmable Parallel 2-D Image Filter CMOS IC Based on the Gilbert Multiplier

Rafal Tomasz Dlugosz

A novel analogue power-efficient 2-D programmable finite impulse response image filter is proposed. This solution is based on the current-mode Gilbert-vector-multiplier operating in the weak inversion region, which allows for ultra low power operation. The ...

Lossy Source Coding with Gaussian or Erased Side-Information

Emre Telatar, Suhas Diggavi, Etienne Perron

In this paper we find properties that are shared between two seemingly unrelated lossy source coding setups with side information. The first setup is when the source and side information are jointly Gaussian and the distortion measure is quadratic. The sec ...

A Fast Thresholded Landweber Algorithm for Wavelet-Regularized Multidimensional Deconvolution

Michaël Unser, Cédric René Jean Vonesch

We present a fast variational deconvolution algorithm that minimizes a quadratic data term subject to a regularization on the

\ell ^{ 1 }

-norm of the wavelet coefficients of the solution. Previously available methods have essentially consisted in alte ...
