Abstract
There are many natural phenomena displayed as polygonal tessellations on curved surfaces, typically found in fruit skin patterns. The paper proposes a method to fit given tessellations with spherical Laguerre Voronoi diagrams. The main target of this paper is fruit skin patterns such as jackfruit and lychee covered by tessellation patterns in which each cell contains a unique spike dot that can be considered as a generator. The problem of estimating the weights is reduced to an optimization problem, and can be solved efficiently. The experiments were done with ideal data and real fruit skin data, which show the validity of the method. We also propose related problems for further studies.
