Lifting-based multi-view image coding
—A number of lifting-based video coding schemes have been recently proposed for scalable video coding. In this paper, we present a novel multi-view image codec based on a wavelet...

Theoretical Model of the Coding Error in MCWT Video Coders
In motion-compensated wavelet based video coders (MCWT), it is known that a precise motion estimation is necessary to minimize the wavelet coefficients energy. However, a motion v...

Three-dimensional shape-adaptive discrete wavelet transforms for efficient object-based video coding
In this paper, we present an object-based coding scheme using three-dimensional shape-adaptive discrete wavelet transforms (SA-DWT). Rather than straightforward extension of 2D SA...

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, ...
