Scalable coding of variable size blocks motion vectors
In this paper we discuss an algorithm that is able to provide a scalable (multiresolution) representation of the motion field information. It has been recently demonstrated that, ...

Fast in-band motion estimation with variable size block matching
In this paper we propose a fast motion estimation technique that works in the wavelet domain. The computational cost of the algorithm turns out to be proportional to the linear si...

Spatial scalability and compression efficiency within a flexible motion compensated 3D-DWT
We investigate the implications of the conventional "t+2D" MC 3D-DWT structure for spatial scalability, and propose a more exible "2D+t+2D" structure. An initi...

An efficient content-adaptive MC 3D-DWT with enhanced spatial and temporal scalability
In this paper we propose a novel, adaptive method for motion compensated 3D wavelet transformation (MC 3D-DWT) of video. The proposed method overcomes problems of ghosting and non...

Model-based MPEG compression of synthetic video sequences
The paper addresses the problem of improving the MPEG compression of synthetic video sequences by exploiting the knowledge about the original 3D model. Two techniques are proposed...
