    Abstract

    A non-photorealistic rendering (NPR) method is presented for generating stippling on the basis of multiplicatively weighted centroidal Voronoi tessellations (CVT). Multiplicative weights are set and updated on the basis of the position of generating points and pixel values of an input image. This paper presents three kinds of multiplicative weights, that is, fixed, variable and monotonically nondecreasing ones. Experimental results show that the stipplings generated by the present method have sharper edges than that by multiplicatively unweighted CVTs.
