The course broadens topics of the image processing course NPGR002 and it is aimed for students eager to gain deeper knowledge in the field. The majority of image processing tasks can be formulated as a variational problem. We give an introduction to the calculus of variations and numerical methods solving optimization problems. Then we focus on problems from image processing, which one can formulate as an optimization problem and we illustrate possible solutions on a wide variety of practical applications.

  • calculus of variations (history, Euler-Lagrange equation, brachistochrone problem, Lagrangien, functions of bounded variation)
  • numerical methods (partial differential equations, finite elements, finite differences, steepest descent, conjugate gradients, quadratic programming)
  • approximation of functions
  • image registration (TPS - thin plate spline)
  • image reconstruction (denoising, deconvolution, regularization with total variation, reconstruction of medical data)
  • image segmentation (Mumford-Shah functional, active contours, method of level-sets, classification)
  • motion detection (optical flow)
  • clustering, feature selection
