This paper deals with new advances made in the field of discrete spatio-temporal filters applied to digital image sequences. Within time-varying images, the temporal correlation of the information is folded within the spatio-temporal domain by motion

The number of regions and length of contour are two basic constraints in segmentation-based motion-compensated video coding. This paper presents a coding scheme which focuses on region number reduction, contour coding, and displaced frame difference

International audience; We propose a new hierarchical approach for lossless and near-lossless resolution scalable compression. It combines the adaptability of DPCM schemes with new hierarchical oriented predictors in order to provide resolution scala

We have investigated an original motion estimation method that exploits several frequency subbands of wavelet pyramids using a multigrid-multiconstraint strategy. A recursive and iterative solution based on the Wiener approach allows to take into acc

We present in this paper an algorithm for motion estimation pel by pel in a sequence of television pictures. This estimator which will be used for a motion compensated coding, must be fitted any type of scene or motion. Techniques we used, are adapta

This paper describes a new method which combines vector quantization (VQ) and orthogonal transform coding schemes. The use of these two techniques in image coding allows efficient bit-rate reduction (about 8-10) with an original-like reconstruction q

Progressive image transmission (PIT) techniques using the multiresolution wavelet decomposition are extended to other wavelet packet bases. Theses techniques are based on progressive selection and progressive quantization of subbands, with fixed or v

In this paper we address an important issue in motion analysis: the detection of moving objects. A statistical approach is adopted in order to formulate the problem. The inter-frame difference is modeled by a mixture of Laplacian distributions, and a

In this paper we present an approach of selective compression of an image sequence based on a priori selection of region(s) of interest (ROI). This method relies on a given motion-based segmentation analysis. The problem of selective compression base
