Robust Structured Low-Rank Approximation on the Grassmannian
Clemens Hage, Martin Kleinsteuber
Over the past years Robust PCA has been established as a standard tool for reliable low-rank approximation of matrices in the presence of outliers. Recently, the Robust PCA approac…
Sparse DOA Estimation of Wideband Sound Sources Using Circular Harmonics
Clemens Hage, Tim Habigt, Martin Kleinsteuber
Sparse signal models are in the focus of recent developments in narrowband DOA estimation. Applying these methods to localizing audio sources, however, is challenging due to the wi…
pROST : A Smoothed Lp-norm Robust Online Subspace Tracking Method for Realtime Background Subtraction in Video
Florian Seidel, Clemens Hage, Martin Kleinsteuber
An increasing number of methods for background subtraction use Robust PCA to identify sparse foreground objects. While many algorithms use the L1-norm as a convex relaxation of the…
Robust PCA and subspace tracking from incomplete observations using L0-surrogates
Clemens Hage, Martin Kleinsteuber
Many applications in data analysis rely on the decomposition of a data matrix into a low-rank and a sparse component. Existing methods that tackle this task use the nuclear norm an…
