Visual markers, or fiducials, have become one of the most common methods of camera pose estimation in Augmented Reality (AR) media. Many present day fiducial-based AR systems us...
We developed the facial caricaturing robot "COOPER" that was exhibited at the Prototype Robot Exhibition of EXPO 2005, Aichi Japan during 11 days from Jun.9 to Jun.19. C...
We aim to reconstruct three-dimensional polyhedra from axonometric line drawings. Existence of mirror symmetry in polyhedra can assist the reconstruction process. We present a new...
