Keywords: Hamilton-Jacobi equations Shape-from-X problems non-Lambertian reflectance models numerical methods for PDEs Image processing applications Mathematical Issues for 3D Printing

Analysis and approximation of Hamilton-Jacobi equations, with particular attention to applications in Image Processing. In particular: 

  • Shape-from-X problems (mainly Shape-from-Shading and Shape-from-Polarisation, using non-Lambertian reflectance models)
  • Multi-View and Photometric Stereo Shape-from-X problems
  • Image Segmentation
  • Image Denoising
  • Image Inpainting

Mathematical modelling for problems related to 3D printers of objects (infill, appearance, overhang, etc.)

Mathematical modelling for thermal insulation problems.

 

Numerical techniques for PDEs: Semi-Lagrangian schemes, Finite Difference schemes, Finite Element Method, acceleration techniques (like e.g. Fast Marching and Fast Sweeping), “Filtered” Schemes (a mixture of a High-order scheme and a monotone one)
