Two-Stage volumetric texture synthesis based on structural information

Volumetric texture synthesis is mainly used in computer graphics for texturing objects in order to increase the realism of the 3D scenario. It is also of particular interest in many application domains such as studying the three-dimensional internal structure of materials and modelling volumetric data obtained by 3D imaging techniques for medical purposes. Based on a previously proposed 2D structure/texture synthesis algorithm, this paper proposes a two-stage 3D texture synthesis approach where the volumetric structure layer of the input texture is first synthesized, then used to help the synthesis of the volumetric texture. Results show that, using the structural information helps the synthesis of the volumetric texture and can outperform the synthesis based only on intensity information.
