Automatic Relocalisation for a Single-Camera Simultaneous Localisation and Mapping System
Abstract— We describe a fast method to relocalise a monocular visual SLAM (Simultaneous Localisation and Mapping) system after tracking failure. The monocular SLAM system stores ...

Robust 2D-3D alignment based on geometrical consistency
This paper presents a new registration algorithm of a 2D image and a 3D geometrical model, which is robust for initial registration errors, for reconstructing a realistic 3D model...

Fast full search block motion estimation for H.264/AVC with multilevel successive elimination algorithm
We modify the multilevel successive elimination algorithm (MSEA) to make it compatible with the motion estimation required for the H.264/AVC video coding standard. The algorithm m...
