Extremal Distance Maintenance for Parametric Curves and Surfaces
A new extremal distance tracking algorithm is presented for parametric curves and surfaces undergoing rigid body motion. The essentially geometric extremization problem is transfo...

Dynamic visibility checking for vision-based motion planning
— An important problem in position-based visual servoing (PBVS) is to guarantee that a target will remain within the field of view for the duration of the task. In this paper, w...

Real-Time Estimation of Dominant Motion in Underwater Video Images for Dynamic Positioning
In this paper, we propose a 2D visual motion estimation method which can be exploited to achieve a dynamic positioning (eg. by gaze control) with respect to a sea-bottom area of i...
