Item Gaming in Elliptic Geometry(The Eurographics Association, 2021) Szirmay-Kalos, Laszlo; Magdics, Milán; Theisel, Holger and Wimmer, MichaelAn interesting way to explore curved spaces is to play games governed by the rules of non-Euclidean geometries. However, modeling tools and game engines are developed with Euclidean geometry in mind. This paper addresses the problem of porting a game from Euclidean to elliptic geometry. We consider primarily the geometric calculations and the transformation pipeline.Item Bregman Approach to Single Image De-Raining(The Eurographics Association, 2021) Szirmay-Kalos, Laszlo; Tóth, Márton; Theisel, Holger and Wimmer, MichaelSurveillance cameras are expected to work also in bad visibility conditions, which requires algorithmic solutions to improve the captured image and to eliminate image degradation caused by these weather conditions. Algorithms for such tasks belong to the field of computational photography and have been successful in eliminating haze, fog, motion blur, etc. This paper presents a simple algorithm to suppress rain or snow from single images. The algorithm uses energy minimization, and we propose a novel data term and a Bregman distance based regularization term reflecting the particular properties of precipitation.
