Course Introduction:                                            

This lecture aims at understanding implementation issues on international image/video standards such as JPEG, MPEG, H.264,… and taking practical lab exercises coded in Visual Studion and C. Lecturer will conduct every day workshop discussing functional issues in the source code and supervising a practical course. Some background reading on digital image processing and information theory is preferably recommended as prerequisites in this course.
