  • motivation: basic problems of image processing (image restoration: denoising, removal of blur, inpainting; segmentation),
  • convex sets (basic concepts, convex cone, projection and separation theorems),
  • convex functions (basic concepts, continuity of convex functions, convex optimization problems),
  • subgradients (basic concepts, subdifferential calculus, set-valued mappings),
  • duality (Legendre-Fenchel conjugate, Lagrange functions, saddle point problems),
  • numerical optimization methods with application to image processing problems.
