Visual tracking with histograms and articulating blocks
We propose an algorithm for accurate tracking of (articulated) objects using online update of appearance and shape. The challenge here is to model foreground appearance with histo...

Overlapped Block Motion Compensation Based on Irregular Grid
In this work, we propose a hybrid motion compensation integrating the advantages of control grid interpolation (CGI) and overlapped block motion compensation (OBMC). We consider c...

The impulse responses of block shift-invariant systems and their use for demosaicing algorithms
Shift-invariant linear algorithms can be described completely by the algorithm's response to an impulse input. The so called impulse response can be used as filter kernels wh...

Sparse Gaussian graphical models with unknown block structure
Recent work has shown that one can learn the structure of Gaussian Graphical Models by imposing an L1 penalty on the precision matrix, and then using efficient convex optimization...

Higher-Order Masking and Shuffling for Software Implementations of Block Ciphers
Differential Power Analysis (DPA) is a powerful side channel key recovery attack that efficiently breaks block ciphers implementations. In software, two main techniques are usually...
