We formalize paper fold (origami) by graph rewriting. Origami tion is abstractly described by a rewrite system (O, ), where set of abstract origami’s and is a binary relation on ...
In this paper we consider the problem of monitoring an art gallery modeled as a polygon, the edges of which are arcs of curves. We consider two types of guards: edge guards (these...
Principal curvatures and principal directions are fundamental local geometric properties. They are well defined on smooth surfaces. However, due to the nature as higher order di...
We present an efficient colon flattening algorithm using conformal structure, which is angle-preserving and minimizes the global distortion. Moreover, our algorithm is general w...
The paper informs about rotating line cameras (which capture images of several 100 Megapixel), their use for creating (stereo) panoramas, and how they can be used for texturing cl...
