Not applicable: students failing a unit of assessment resit the assessment in its original format.
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
- 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).
Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
