# COMPUTER VISION & GRAPHICS - 2021/2

Module code: EEE2041

## Module Overview

Expected prior learning**:** Learning equivalent to Year 1, and Year 2 Semester 1, of EE Programmes.

Module purpose: This module provides an introduction to the process of digital image formation in real and computer generated imagery. Mathematical methods used to represent cameras, scene geometry and lighting in both computer vision and graphics are covered. The course provides an introduction to both the theoretical concepts and practical implementation of three-dimensional computer graphics used in visual effects, games and scientific visualisation. Practical implementation of computer graphics will be introduced using the OpenGL libraries which are widely used in industry.

## Assessment Strategy

The **assessment strategy** for this module is designed to provide students with the opportunity to demonstrate the ability to apply mathematical methods used computer graphics and demonstrate the ability to implement interactive computer graphics applications using OpenGL.

Closed book examination is used to assess the ability to explain and apply mathematical methods in computer graphics. Practical assignment evaluated through interactive demonstration and written report is used to assess ability to implement computer graphics applications using OpenGL.

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

· Closed-book written examination assessing understanding of mathematical foundations of computer graphics, use of mathematical methods in solving computer graphics problems and practical implementation of computer graphics in OpenGL [2hours]

· Computer graphics assignment to implement an interactive computer graphics application assessed through in class demonstration and report [50 hours total]

These deadlines are 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.

· Exercise sheets to practice problem solving using mathematical methods presented in lectures. Self-assessment solutions and problem classes are provided for summative assessment.

· Computer graphics practical exercises for guided implemented of interactive computer graphics applications using OpenGL. Practical exercises provide immediate visual feedback on successful implementation.

· Feedback on practical exercises from laboratory supervisors on progress and implementation.

· Self-assessment of progress on assignment against required functionality.

· Feedback on assignment demonstration and final report.

## Methods of Teaching / Learning

The **module learning and teaching strategy** is designed to provide a mathematical foundations of computer graphics together with knowledge of the practical implementation in OpenGL through lecture material reinforced with a structured programme of exercises, laboratory classes and an individual interactive graphics assignment.

**Learning and teaching methods** include the following:

- Lectures covering both mathematical foundations and practical implementation (2 hours per week for 11 weeks).
- Exercises sheets to practice mathematical methods presented in lectures (6 sheets x 3hours per sheet).
- Problem classes in lectures to review solutions to exercise sheets (0.5 hours per week for 6 weeks).
- Computer graphics practical exercises using OpenGL (5 weeks x 1 hour per week supervised laboratory).
- Computer graphics assignment (6 weeks x 1 hour per week supervised laboratory).

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.
