Image Coding

The following materials are part of the teaching given in the Master in Science degree program offered by our department, which is partly centered on image coding. Below, the sources of the presentations (PowerPoint documents) used in some of the sessions are provided. These presentations were done (in part) for the presentation of our research in conferences. Research papers related to each session provide further details of the contents.

These materials are left here in response to many petitions of students and colleagues. Feel free to use them.
