A coded image that is invisible for human observers is temporally integrated into the projected image, but can be reconstructed by a synchronized camera. The embedded code is dynamically adjusted on the fly to guarantee its non-perceivability and to adapt it to the current camera pose. Linked with real-time flash keying, for instance, this enables in-shot optical tracking using a dynamic multi-resolution marker technique. A sample prototype is realized that demonstrates the application of our method in the context of augmentations in television studios.}, subject = {Association for Computing Machinery / Special Interest Group on Graphics}, language = {en} } @article{GrundhoeferSeegerHaentschetal.2007, author = {Grundh{\"o}fer, Anselm and Seeger, Manja and H{\"a}ntsch, Ferry and Bimber, Oliver}, title = {Coded Projection and Illumination for Television Studios}, organization = {Bimber, Fak.
