Reusing the H.264/AVC deblocking filter for efficient spatio-temporal prediction in video coding
The prediction step is a very important part of hybrid video codecs for effectively compressing video sequences. While existing video codecs predict either in temporal or in spati...

Spatial sound reproduction systems using higher order loudspeakers
Sound reproduction systems aim to produce a desired sound field over a region of space. At high frequencies, the number of loudspeakers required is prohibitive. This paper shows t...

From a static impossibility to an adaptive lower bound: the complexity of early deciding set agreement
Set agreement, where processors decisions constitute a set of outputs, is notoriously harder to analyze than consensus where the decisions are restricted to a single output. This ...

Finding Small Roots of Bivariate Integer Polynomial Equations: A Direct Approach
Coppersmith described at Eurocrypt 96 an algorithm for finding small roots of bivariate integer polynomial equations, based on lattice reduction. A simpler algorithm was later pro...

A Greedy Common Subexpression Elimination Algorithm for Implementing FIR Filters
— The complexity of Finite Impulse Response (FIR) filters is dominated by the number of adders (subtractors) used to implement the coefficient multipliers. A greedy Common Subexp...
