Novel fast block motion estimation in feature subspace
Motion estimation and compensation are widely used in video coding. This paper presents two fast block matching algorithms for motion estimation. These algorithms use the subspace...

Multi-channel restoration of electron micrographs
We introduce a projection based multi-channel restoration method which is useful in cases for which there is no a priori information about the input signal. The method is especial...

Adaptive overlapping approach for DCT-based motion estimation
The feedback loop for temporal prediction of traditional implementations of an MPEG-compliant video coder requires conversion of images from the spatial domain to the transform do...

Variable resolution Markov modelling of signal data for image compression
Traditionally, Markov models have not been successfully used for compression of signal data other than binary image data. Due to the fact that exact substring matches in non-binar...

Multigrid adaptive image processing
We consider a general weighted least squares approximation problem with a membrane spline regularization term. The key parameters in this formulation are the weighting factors whi...
