A panoramic image based localisation system has been implemented on a B21r mobile robot and tested in a heavily cluttered environment. It takes vertical object edges as natural la...
In this paper, we present a novel image representation that renders it possible to access natural scenes by local semantic description. Our work is motivated by the continuing effo...
We propose a family of kernels between images, defined as kernels between their respective segmentation graphs. The kernels are based on soft matching of subtree-patterns of the r...
Facial expression interpretation, recognition and analysis is a key issue in visual communication and man to machine interaction. In this paper, we present a technique for extract...
This paper proposes a self-authentication scheme for color images, using a fragile data hiding method based on the Discrete Pascal Transform (DPT). The main contribution of this wo...
