Texture Mapping of 3D Human Face for Virtual Reality Environments

Texture mapping of 3D digitized data is a challenge. This arises mainly due to two factors: i) digitization of geometry and ii) digitization of textures. First, due to digitization of geometry we have a basket of polygons that represent the digitized object. Second, due to digitization of textures, we get another basket of textures that represent the digitized texture of the whole object. Unfortunately, there is little or no correspondence between the digitized geometry and digitized texture. The challenge is to automatically identify the correspondence between the merged geometry and merged texture and then to perform an intelligent texture mapping. In this work, we have shown two procedures that perform 3D texture mapping using a combination of image warping and direct texture mapping.
