Towards jointly optimal spatial prediction and adaptive transform in video/image coding
This paper proposes a new approach to combined spatial (Intra) prediction and adaptive transform coding in block-based video and image compression. Context-adaptive spatial predic...

A New Bit-Plane Entropy Coder for Scalable Image Coding
Compression ratio and computational complexity are two major factors for a successful image coder. By exploring the Laplacian distribution of the wavelet coefficients, a new bit ...

Adaptive correlation estimation for general Wyner-Ziv video coding
Wyner-Ziv video coding (WZVC) is a new paradigm for video compression with the prediction frames possibly only available at the decoder. It exploits the statistics between the sou...

Using H.264/AVC-Intra for Segmentation-Driven Compound Document Coding
In this paper we explore H.264/AVC operating in intraframe mode to compress a mixed image, i.e. composed of text, graphics and pictures. Even though mixed contents (compound) docu...
