Avoiding self-occlusions and preserving visibility by path planning in the image
In this paper, we address the problem of generating trajectories of some image features in order to control efficiently a robotic system using an image-based control strategy. Firs...

A Hierarchical Algorithm for Fast Backprojection in Helical Cone-Beam Tomography
Existing algorithms for exact helical cone beam (HCB) tomographic reconstruction involve a 3-D backprojection step, which dominates the the computational cost of the algorithm. We...

Automated Feature-Based Range Registration of Urban Scenes of Large Scale
We are building a system that can automatically acquire 3D range scans and 2D images to build geometrically and photometrically correct 3D models of urban environments. A major bo...
