The course main objective is to provide general knowledge in multimedia content management. The course builds on previous theoretical assets, e.g. signal processing, information theory, networking and computer science at large, to describe how practical constraints drive design choices of a multimedia system.
This course shall focus more specifically on multimedia contents compression and protection. A practical work (using the C language) on digital image watermarking summarizes most of the issues encountered in the course.
Refresher (probabilities, information theory) Source coding (Huffman, arithmetic, dictionaries) Quantization (scalar, uniform and non uniform, vector quantization, LBG) Elements of image processing (filters: derivative, integral, rank, feature points, noise and its applications) Watermarking (applications, feature vector, quantization vs. BPSK embedding, spread spectrum, side-information, embedding security), traitor tracing (introduction, Tardos probabilistic codes, application to video)
Most of the theoretical tools needed will be summarized during the course.
For the practical work, decent knowledge in C programming in the Unix environment in required.
