Model-based head pose estimation for air-traffic controllers
We present a method for estimating the point of fixation of an air traffic controller from a low resolution video sequence. A geometric model of the head is used to estimate hea...

A priori information in image segmentation: energy functional based on shape statistical model and image information
In this paper, we propose an energy functional to segment objects whose global shape is a priori known thanks to a statistical model. Our work aims at extending the variational ap...

Fast hierarchical backprojection for helical cone-beam tomography
Existing algorithms for exact helical cone beam (HCB) tomographic reconstruction are computationally infeasible for clinical applications. Their computational cost is dominated by...
