3D-shape extraction and reconstruction from Images |

One application
in this area is to provide objects texture with different light source direction.
The principle of this approach is based on “shape from shading”. However, we
treat the case that a light source direction is unknown and texture on the
surface is fine. This operation is performed in the wavelet coefficients
domain.
Another application
is to overlay an image of city landscape on an image projected by 3D-map data
to identify direction and some specific building. Recent mobile phone has a capability of GPS plus digital
camera, so that rough location information and edge image matching enables
this operation.
