Distributed compressed sensing: Sparsity models and reconstruction algorithms using annihilating filter
Consider a scenario where a distributed signal is sparse and is acquired by various sensors that see different versions. Thus, we have a set of sparse signals with both some commo...

Chirp rate estimation of speech based on a time-varying quasi-harmonic model
The speech signal is usually considered as stationary during short analysis time intervals. Though this assumption may be sufficient in some applications, it is not valid for high...

Onset detection in pitched non-percussive music using warping-compensated correlation
Automatically extracting temporal information from musical recordings is inarguably one of the most critical subtasks of many music information retrieval systems. In this paper we...

Concept for Hierarchical and Distributed Processing of Area Based Triggers
Area based triggers denote notifications being generated if a mobile client changes its spatial relation to a defined area, e.g. if it enters or leaves it. By these triggers, new ...
