A multilevel texture mapping process for a 3D model maps different perspective images onto a 3D model. The textures mapped to the 3D model are processed from image level to texture level, then to pixel level, hence, the method eases the edge appearance problem at the boundary where neighboring images are stitched together caused by different lighting and viewing parameters. The result shows that the smooth transition between neighboring textures provides better visual quality than just blending the boundary where neighboring images are stitched.
