Soft Edge and Soft Corner Blending.
Virtuelle und Erweiterte Realität.
Konferenzveröffentlichung, Bibliographie
Kurzbeschreibung (Abstract)
We address artifacts at corners in soft edge blend masks for tiled projector arrays. We compare existing and novel modifications of the commonly used weighting function and analyze the first order discontinuities of the resulting blend masks. In practice, e.g. when the projector lamps are not equally bright or with rear projection screens, these discontinuities may lead to visible artifacts. By using first order continuous weighting functions, we achieve significantly smoother results compared to commonly used blend masks.
