Abstract
We propose a method for generating maze-like images by connecting Voronoi regions using minimum spanning trees that link the generating points of the weighted centroidal Voronoi tessellations. We also propose a brightness correction method for the halftone image based on the hexagonal lattice approximation of the centroidal Voronoi tessellation. Experimental results showed that the obtained halftone images can reproduce the true continuous tone of input images.
