Feature-Based Texture Synthesis using Voronoi Diagrams

In this technical report, we present a technique to synthesize featured textures easily and interactively. The main idea is to synthesize the texture by copying irregular patches from the source to the target texture, each of them containing a complete feature. The interior part of the feature is not touched while the cutting and stitching is done 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 synthesises the target texture by copying and stitching patches of the target’s Voronoi cellular shapes from the source texture.
