RGBD Relocalisation Using Pairwise Geometry and Concise Key Point Sets

We describe a novel RGBD relocalisation algorithm based on key point matching. It combines two com- ponents. First, a graph matching algorithm which takes into account the pairwise 3-D geometry amongst the key points, giving…

Estimating Visual Attention from a head-mounted IMU

We are developing  methods for the estimation of both temporal and spatial visual attention using a head-worn inertial measurement unit (IMU). Aimed at tasks where there is a wearer-object interaction, we estimate the when and…

Automated Fin Identification of Individual Great White Sharks

The objective of this work is automatically to identify individual great white sharks in a database of thousands of unconstrained fin images. The approach put forward appreciates shark fins in natural imagery as smooth, flexible…
