This paper presents an efficient method for extracting the skeleton of a planar shape. The method is based on computing local symmetries of the shape’s linearized contour. The ce...
Using the achievements of my research group over the last 30+ years, I provide evidence to support the following hypothesis: By complementing each other, cooperating reasoning pro...
Many attempts have been made to represent families of 2D shapes in a simpler way. These approaches lead to so-called structures as the Symmetry Set (SS) and a subset of it, the Med...
This paper examines the notion of symmetry in Markov decision processes (MDPs). We define symmetry for an MDP and show how it can be exploited for more effective learning in singl...
We investigate the problem of producing symmetric tilings by programs in a uniform way. By this, we mean that the construction of a tiling should be parameterized by the geometric...
