Recognising facial expressions in video sequences
Abstract We introduce a system that processes a sequence of images of a front-facing human face and recognises a set of facial expressions. We use an efficient appearance-based fac...

Power reduction techniques for multiple-subcarrier modulated diffuse wireless optical channels
In this paper, two novel techniques are proposed to reduce the average optical power in wireless optical multiplesubcarrier modulated (MSM) systems, namely in-band trellis coding a...

3D Pose Estimation and Segmentation using Specular Cues
We present a system for fast model-based segmentation and 3D pose estimation of specular objects using appearance based specular features. We use observed (a) specular reflection...

Online camera pose estimation in partially known and dynamic scenes
One of the key requirements of augmented reality systems is a robust real-time camera pose estimation. In this paper we present a robust approach, which does neither depend on of...
