要旨:
We present a novel real-time approach for user-guided intrinsic decomposition
of static scenes captured by an RGB-D sensor. In the
first step, we acquire a three-dimensional representation of the scene
using a dense volumetric reconstruction framework. The obtained
reconstruction serves as a proxy to densely fuse reflectance estimates
and to store user-provided constraints in three-dimensional space.
User constraints, in the form of constant shading and reflectance
strokes, can be placed directly on the real-world geometry using
an intuitive touch-based interaction metaphor, or using interactive
mouse strokes. Fusing the decomposition results and constraints in
three-dimensional space allows for robust propagation of this information
to novel views by re-projection.We leverage this information
to improve on the decomposition quality of existing intrinsic video
decomposition techniques by further constraining the ill-posed decomposition
problem. In addition to improved decomposition quality,
we show a variety of live augmented reality applications such as
recoloring of objects, relighting of scenes and editing of material
appearance.
