Course content

  • Introduction: examples of application of the image processing from several domains, medical applications, industry, HCI...
  • Human vision fundamentals 
  • Acquisition
  • Definitions : the image processing chain
  • Quantification : spatial, spectral and intensity color representation different acquisition modalities sensor,sensor+source,...
  • Acquisition devices : CCD, CMOS, vidicon ultrasound light time-of-flight (TOF)
  • Notions of compression : run-length-coding, hierarchical decomposition, Jpeg lossy compression
  • Pre-processing - Histogram based image enhancement
  • Linear filtering Fourier transform
  • Fourier domain processing : e.g. interlaced image correction pattern matching
  • Image restoration : Wiener filtering rank filter
  • Morphomatematics definitions : ensemble, structuring element

Evaluation

Method(s) of evaluation

  • Other

  • The evaluation of the practical work will be done on the basis of a series of assignments to be handed in during the term.
  • Oral exam without note, depending on the circumstances, exam can be done remotely using Teams.

Mark calculation method (including weighting of intermediary marks)

80% oral exam + 20% on the quality of Practice work
oral exam (2 questions without notes)

  • 1 theory question 50%
  • 1 problem based question 50%

Language(s) of evaluation

  • english
  • (if applicable french )
