ELEC70078 Digital Image Processing
Lecturer(s): Dr Tania Stathaki; Prof Patrick Naylor
In this module, you will examine the fundamental digital image analysis and processing concepts and analytical methods that mainly stem from a digital signal processing approach. Areas discussed include image representation and storage, filtering and transform techniques for image processing including two dimensional Fourier transforms, techniques for noise reduction, image enhancement, coding and compression techniques, and lossy versus lossless compression.
On successful completion of this module, you should be able to: 1. use analytical methods in digital image processing. 2. apply, evaluate and compare various Image Transform models. 3. apply, evaluate and compare various Image Enhancement and Image Restoration techniques. 4. implement different Image Compression techniques. 5. apply the techniques taught in the course to real-life scenarios, interpret the results obtained and propose solutions for further improvements.
