Expected learning outcomes

On completion of this course the student will be able to:

Knowledge  

  • Posses an understanding of the fundamental characteristics of digital systems used in imaging, together with general concepts of science, quantitative methods.
  • Possess advanced knowledge of basic algorithms for image manipulation, characterization, filtering, segmentation, feature extraction and template matching in direct space and Fourier space.
  • Posses advanced knowledge of (i.e. to describe, analyse and reason about) how monochrome digital images are represented, manipulated, encoded and processed, with emphasis on algorithm design, implementation and performance evaluation.
  • Possess advanced knowledge of methods of capturing and reproducing images in digital systems.
  • Possess specialized insight and good understanding of the research frontier in a selected part of the media technology area.

Skills  

  • Are able to use mathematical techniques in colour imaging and demonstrate the use of tools such as spreadsheets and specialist maths applications to solve problems in colour imaging.
  • Are able to to explore a range of practical techniques, by developing their own simple processing functions using library facilities and tools such as Matlab.
