Visual Media Compression

In this course, fundamental algorithms for compression of image and video are introduced, such as transform coding, quantization rate-distortion optimization, and entropy coding. This course will also review the fundamental techniques to compress 3D contents in different formats: multiview video, and 3D mesh / point clouds. The course will also provide knowledge to understand the state-of-the-art video compression standards. Finally, new trends in visual media compression, such as compression using neural networks, and compression of plenoptic video contents are also introduced. This course will consist of three parts: a theoretical one, a practical one and project work. The course content will be as follows:

• Review of Image / video processing tools
• Why compression, and its history
• Lossless and lossy coding, scalability
• Transform coding, Quantization, entropy coding
• Prediction models, Rate-distortion optimization
• JPEG and MPEG standards
• 3D video compression techniques and Standards
• Compression by neural networks
• Plenoptic video and compression techniques
• Future trends in visual media compression

• Understand compression algorithms
• Develop a single tool compression, and
• Use existing, advanced compression tools

Connaissances et compétences pré-requises ou co-requises

• Knowledge in programming using C / C ++, Python or MATLAB
• Weak prerequisites: basic knowledge in image / video processing

Theoretical (50%) / practical (50%) teaching and assignments, followed by project work presentation
