Module Specifications.
Current Academic Year 2024 - 2025
All Module information is indicative, and this portal is an interim interface pending the full upgrade of Coursebuilder and subsequent integration to the new DCU Student Information System (DCU Key).
As such, this is a point in time view of data which will be refreshed periodically. Some fields/data may not yet be available pending the completion of the full Coursebuilder upgrade and integration project. We will post status updates as they become available. Thank you for your patience and understanding.

Description To give the student a practical understanding of digital image synthesis and analysis | |||||||||||||||||||||||||||||||||||||||||||
|
Learning Outcomes 1. Understand and analyse the computer graphics pipeline - 3D geometric primitives, 3D transformation, camera transformation, lighting, projection, clipping, rasterisation. 2. Understand the operation of a 3D computer graphics API - including translation, rotation and scaling of 3D objects, primitives (points, lines, polygons), attributes (size, colour), projection, illumination, animation 3. Design and program an application using a 3D graphics API - including the various function libraries, the range of functions for describing the 3D scene, projection onto a 2D viewing surface, control of the display window, interactivity including events and callbacks, hidden surface removal 4. Analyse digital images using the Fourier Transform algorithm - including an understanding of the space and frequency domains, high-pass and low-pass filtering, texture detection, shifting and scaling 5. Understand and apply the Convolution Theorem - including the concepts of linear shift-invariance, impulse response, the connection between convolution and Fourier Transforms, high- and low-pass filtering viewed as a convolution 6. Apply the concepts of sampling and replication - how sampling an image leads to replication in the Fourier domain, using convolution to increase the resolution of an image, anti-aliasing to reduce artifacts when an image is downsampled | |||||||||||||||||||||||||||||||||||||||||||
