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…

In-situ interactive model building

The current system allows online building of 3D wireframe models through a combination of user interaction and automated methods from a handheld camera-mouse. Crucially, the model being built is used to concurrently compute camera pose,…

Situation awareness through hand behaviour analysis

Activity recognition and event classification are of prime relevance to any intelligent system designed to assist on the move. There have been several systems aimed at the capturing of signals from a wearable computer with…

Fast and robust local feature detectors

At the moment we are working on fast and robust local feature detectors and descriptors, supported by a HP Labs Innovation Research Award for Dr Walterio Mayol-Cuevas’ proposal titled ‘Anywhere Authoring using Interactive Computer Vision and Mobile…

Towards Robust Real-time Visual SLAM

Our project investigates how to improve feature matching within a single camera Real-time Visual SLAM system. SLAM stands for Simultaneous Localisation and Mapping, when a camera position is estimated simultaneously with sparse point-wise representation of a…

ViewNet

Context enhanced networked services by fusing mobile vision and location ViewNet is a 1.5M GBP project jointly funded by the UK Technology Strategy Board, the EPSRC and industrial partners. The aim is to develop the…

Visual SLAM

Simultaneous localisation and mapping (SLAM) is the problem of determining the position of an entity (localisation), such as a robot, whilst at the same time determining the structure of the surrounding environment (mapping). This has been a major topic…

Bio-Inspired 3D Mapping

Geoffrey Daniels Supervised by: David Bull, Walterio Mayol-Cuevas, J Burn Using state of the art computer vision techniques and insights into the biological process used by animals to traverse any terrain a system has been…
