SUMMARY: (...): Anisotropic approaches for imaging problems adapted to huma
 n visual perception
DESCRIPTION:: The use of anisotropic approaches has a long tradition in the
  imaging community. Historically\, such methods date back to the seminal w
 ork of J. Weickert where PDEs based on anisotropic diffusion were applied 
 to solve several image restoration models such as denoising\, deblurring e
 tc. Recently\, the use of directional models has been reinterpreted for th
 e design of new image regularisers and applied to a wide variety of imagin
 g tasks due to their better behaviour in terms of structure and geometry p
 reservation. In the first part of this talk\, I will review the main contr
 ibutions in this field and present my recent work on this topic discussing
  the use of the anisotropic osmosis PDE in several contrast-equalisation a
 nd shadow removal problems. In the second part of the talk\, I will connec
 t the connections between these classical approaches to my ongoing work on
  cortical-inspired contrast and color perception models where the local an
 isotropy (i.e. orientation) in the image appears naturally as a result of 
 a `lifting’ procedure extending the image from a bi- to a three-dimensio
 nal space.http://sites.google.com/view/lucacalatroni/home
