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 gshape from shadingh. 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.
