On the Reprojection of 3D and 2D Scenes Without Explicit Model Selection
It is known that recovering projection matrices from planar con gurations is ambiguous, thus, posing the problem of model selection | is the scene planar 2D or non-planar 3D? For ...

An approach to 2D/3D registration of a vertebra in 2D X-ray fluoroscopies with 3D CT images
In order to use pre-operative images during an operation for navigation, they must be registered to the patient's coordinate system in the operating theater or to an intra-ope...
