New lower bounds for the number of straight-edge triangulations of a planar point set
(2004)We present new lower bounds on the number of straight-edge triangulations that every set of n points in plane must have. These bounds are better than previous bounds in case of sets with either many or few extreme points.

Non-local regularization of the reverse heat equation for digital images enhancement
(2007-09)In 1955 Kovasznay et al. proposed to enhance an image by reversing the heat equation. This process is highly unstable and ...
