Relief occlusion-adaptive meshes for 3D imaging

Image morphing, which is a 2D imaging technique, allows smooth transition between images. However, a limitation of existing image morphing techniques is the lack of user interaction. Another limitation is that shape warping often causes distortion due to barycentric mapping. In this paper, we present a novel 3D morphological technique to address these problems. A new concept of relief occlusionadaptive meshes is introduced, allowing a user to change the viewpoint of the output images in the morphing process. By making use of the intrinsic geometric relationship among the reference images for projective transformation, the distortion due to barycentric mapping is prevented. Unlike other warping-based view transferring techniques, our morphological technique provides very smooth transition between reference images and supports both rigid and non-rigid scenes.
