BITPEER: continuous subspace skyline computation with distributed bitmap indexes
In this paper, we propose a bitmap approach for efficient subspace skyline computation in a distributed setting. Our approach computes extended skylines which have been shown to i...

Propagator-based methods for recursive subspace model identification
The problem of the online identification of multi-input multi-output (MIMO) state-space models in the framework of discrete-time subspace methods is considered in this paper. Seve...

Robust Clustering in Arbitrarily Oriented Subspaces
In this paper, we propose an efficient and effective method to find arbitrarily oriented subspace clusters by mapping the data space to a parameter space defining the set of possi...

Multi-Frame Optical Flow Estimation using Subspace Constraints
We show that the set of all ow- elds in a sequence of frames imaging a rigid scene resides in a lowdimensional linear subspace. Based on this observation, we develop a method for ...
