Image & Video Compression

[ImCod]
T Technical Teaching


Abstract

Because multimedia data (in particular image and video) require efficient compression techniques in order to be stored and delivered, image and video compression is a crucial element of an effective communication system.

This course covers the most popular lossless and lossy formats, introduces the key techniques used in source coding, as well as appropriate objective/subjective metrics for visual quality evaluation.

Teaching and Learning Methods: Each class includes a problem session for students to practice the material learned. This course includes a limited number of lab session hours.

Course Policies: It is mandatory to attend lab. sessions.

Requirements

It would be good if you already have some knowledge about signal/image processing and Matlab, but it is not mandatory.
