2. Very low bitrate facial video coding : based on principal component analysis
Abstract : This thesis introduces a coding scheme for very low bitrate video coding through the aid of principal component analysis. Principal information of the facial mimic for a person can be extracted and stored in an Eigenspace. Entire video frames of this persons face can then be compressed with the Eigenspace to only a few projection coefficients. READ MORE

3. Model-based head tracking and coding
Abstract : This thesis treats two topics in model-based coding; coding of facial textures (Part 1) and real-time head tracking (Part 2).In Part 1, it is shown that a face image can be efficiently coded using a parameterization based on geometrical normalization followed by Karhunen-Loeve transformation (KLT).
