Improvement to the Minimization of Hybrid Error Functions for Pose Alignment
— Many problems in computer vision such as pose recovery and structure estimation are formulated as a minimization process. These problems vary in the use of image measurements d...

Image-based Control of Mobile Robot with Central Catadioptric Cameras
— To close the loop between motion and vision, tracked visual features must remain in the camera field of view (visibility constraint). To overcome the visibility constraint, vi...

Designing a tone mapping algorithm for road visibility experiments
In this paper, we propose a tone mapping operator based on a multiscale representation pattern and on thresholds of detection contrast computed for local adaptation luminances. Th...

Person Spotting: Video Shot Retrieval for Face Sets
Matching people based on their imaged face is hard because of the well known problems of illumination, pose, size and expression variation. Indeed these variations can exceed those...
