Filtered Blending: A new, minimal Reconstruction Filter for Ghosting-Free Projective Texturing with Multiple Images

Whenever approximate 3D geometry is projectively texture-mapped from different directions simultane- ously, annoyingly visible aliasing artifacts are the result. To prevent such ghosting in projective tex- turing and image-based rendering, we propose a new GPU-based rendering strategy and a new, view- dependent denition 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 efciently eliminated at real-time rendering frame rates on standard graphics hardware. With the pro- posed rendering technique, better-quality rendering results are obtained from fewer images and coarser 3D geometry.
