Module overview

Expected prior learning:  None specifically advised.

Module purpose:  This module introduces basic notions of rate-distortion theory applied to the compression of digitised still images and moving sequences,  provides high-level descriptions of mainstream algorithms for coding and error resilience and offers an overview of the main features, components and algorithmic tools involved in current international standards for image and video compression and error resilience in multimedia applications.


Module aims

to provide an understanding of the principles underlying the compression of image and video signals

to provide in-depth knowledge of state-of-the-art coding techniques, internationally standardised compression algorithms, error resilience techniques and related systems and technology.

Methods of Teaching / Learning

The learning and teaching strategy is designed to achieve the specified learning outcomes by teaching the module syllabus in lectures, and supporting the assimilation and understanding of the taught material by the supervised lab classes. The practical design and technical skills related to the subject are acquired through coursework involving an assignment on image and video compression system design, and then the performance characterisation of the designed system through laboratory experiments.

Learning and teaching methods include:

Lectures: 10 weeks, 3 hours per week.
Design Labs: Image and Video Codec design. This design assignment is based on laboratory sessions that take place for five weeks, from Week 5 to Week 9. These provide the technical skills and expertise required for performance characterisation of state-of-the-art image and video systems. Students then have to produce a technical report that is submitted in Week 10 (see below).



Assessment Strategy

The assessment strategy for this module is designed to provide students with the opportunity to demonstrate the learning outcomes. The written examination will assess the knowledge and assimilation of terminology, concepts and theories of image and video compression, as well as the ability to analyse state-of-the-art image and video codecs and how to use them for present communications systems. The design assignment will assess the ability to design video communications systems, including the related technical skills acquired in the laboratory work.


Thus, the summative assessment for this module consists of the following.

·         2-hour, closed-book written examination

·         Image and Video Codec design. A multi-part assignment involving the design of a image and video system, as assessed by a final technical report (10-20 pages), that has to be submitted by Tuesday of Week 10.


Note that any deadline given here is indicative. For confirmation of exact date and time, please check the Departmental assessment calendar issued to you.


Formative assessment and feedback


For the module, students will receive formative assessment/feedback in the following ways.

·         During lectures, by question and answer sessions

·         Being a part of the interactive lectures

·         During lectures, by problem solving

·         During tutorials/tutorial classes

·         During supervised laboratory sessions

·         During supervised computer laboratory sessions

·         Via the marking of written reports

·         Via assessed coursework
