Whenever approximate 3D geometry is projectively texture-mapped from different directions simultaneously, annoyingly visible aliasing artifacts are the result. To prevent such ghosting in projective texturing and image-based rendering, we propose a new GPU-based rendering strategy and a new, viewdependent definition of ghosting. The algorithm is applicable to any kind of image-based rendering method, or general projective texture mapping, and adapts to arbitrary camera setups. It is able to cope with imprecise 3D geometry. Ghosting artifacts are efficiently eliminated at real-time rendering frame rates on standard graphics hardware. With the proposed rendering technique, better-quality rendering results are obtained from fewer images and coarser 3D geometry.
