1. Model Based Coding : Initialization, Parameter Extraction and Evaluation
Abstract : This thesis covers topics relevant to model-based coding. Model-based coding is a promising very low bit rate video coding technique. The idea behind this technique is to parameterize a talking head and to extract and transmit the parameters describing facial movements. At the receiver, the parameters are used to reconstruct the talking head. READ MORE

2. Coding of three-dimensional video content : Depth image coding by diffusion
Abstract : Three-dimensional (3D) movies in theaters have become a massive commercial success during recent years, and it is likely that, with the advancement of display technologies and the production of 3D contents, TV broadcasting in 3D will play an important role in home entertainments in the not too distant future. 3D video contents contain at least two views from different perspectives for the left and the right eye of viewers.

3. A Universal Source Coding Perspective on PPM
Abstract : The PPM (Prediction by Partial Matching) family of text compression algorithms has several members that have shown to be very efficient in practice. This thesis treats PPM algorithms from an information-theoretical point of view, based on results and methods from universal source coding theory. READ MORE

4. Coding, Computing, and Communication in Distributed Storage Systems
Abstract : Conventional studies in communication networks mostly focus on securely and reliably transmitting data from a source node (or multiple source nodes) to multiple destinations. A more general problem appears when the destination nodes are interested in obtaining functions of the data available in distributed source nodes. READ MORE

5. Efficient Coding Techniques for Networks & Channels with Transmission Errors
Abstract : This thesis consists of two parts, both of whichinvestigate coding techniques for information transmission throughchannels in the presence of errors. Part I discusses topics ofnetwork coding and rateless codes. Part~II considers channel codesfor continuous phase modulation. These two parts are clearlydifferent, but they are also related. READ MORE
