Abstract
In this paper, we present a technique to synthesize featured textures easily and interactively. The main idea is to synthesize a new texture by copying irregular patches from the source to the target texture, each of which contains a complete feature. The interior part of the feature is not touched while the cutting and stitching is performed on the background texture between the features. The technique starts by selecting a feature in the source texture by the user, after which the algorithm finds the positions of other features, generates a similar distribution of features, and finally synthesizes the target texture by copying and stitching patches of the target’s Voronoi cellular shapes from the source texture. The technique is fast enough to be used interactively to edit textures in a simple and easy way. KEY WORDS Texture editing, Voronoi diagrams, Image synthesis.
