Computer graphics applications often use textures to decorate virtual objects in order to increase realism without modifying geometric details. In recent years, texture synthesis has been a useful tool to generate large textures starting from a sample texture. Texture synthesis is also used to fill holes in damaged pictures, or to generate illimitable textures in interactive applications such as games and simulators. In our book, we present our contributions in texture synthesis and editing. The contributions are in three directions, a pixel-based texture synthesis technique, a patch-based texture synthesis technique, and a patch-based texture synthesis and editing technique. In our texture-editing technique, irregular patches are copied from the source texture and stitched in the target texture based on the Voronoi diagram cells around main features. The interior part of the feature is not touched, while the cutting and stitching is performed on the background between the features. The technique is fast enough to be used interactively and to edit textures in a simple and easy way.
