EBWIC: A low Complexity and Efficient Rate Constrained Wavelet Image Coder
Efficient compression algorithms generally use wavelet transforms. They try to exploit all the signal dependencies that can appear inside and across the different sub-bands of th...

Real-Time Very Low Bit Rate Video Coding with Adaptive Mean-Removed Vector Quantization
This is a contribution for very low bit rate video coding in real-time and software only on computers of PC class. It is based on frame replenishment with block coding using mean-...

Blocking Artefact Free Video Coding Based on a Bilinear Forward Image Warping Model
In this paper a new very low bit rate video coding scheme is presented. It is based on a forward motion estimation technique using an image warping model, thus delivering the basi...

Reduced DCT approximations for low bit rate coding
Transform approximations are explored for speeding up the software compression of images and video. Faster approximations are used to replace the regular DCT whenever only few DCT...
