Stability, well-posedness and regularity of the homogeneous Landau equation for hard potentials
Nicolas Fournier, Daniel Heydecker
We establish the well-posedness and some quantitative stability of the spatially homogeneous Landau equation for hard potentials, using some specific Monge-Kantorovich cost, assumi…
Dynamic Spectral Residual Superpixels
Jianchao Zhang, Angelica I. Aviles-Rivero, Daniel Heydecker +3
We consider the problem of segmenting an image into superpixels in the context of -means clustering, in which we wish to decompose an image into local, homogeneous regions corre…
Bilinear Coagulation Equations
Daniel Heydecker, Robert I. A. Patterson
We consider coagulation equations of Smoluchowski or Flory type where the total merge rate has a bilinear form for a vector of conserved quantities , generalis…
Mirror, Mirror, on the Wall, Who's Got the Clearest Image of Them All? - A Tailored Approach to Single Image Reflection Removal
Daniel Heydecker, Georg Maierhofer, Angelica I. Aviles-Rivero +4
Removing reflection artefacts from a single image is a problem of both theoretical and practical interest, which still presents challenges because of the massively ill-posed nature…
Peekaboo - Where are the Objects? Structure Adjusting Superpixels
Georg Maierhofer, Daniel Heydecker, Angelica I. Aviles-Rivero +2
This paper addresses the search for a fast and meaningful image segmentation in the context of -means clustering. The proposed method builds on a widely-used local version of Ll…
