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…

Place Recognition From Disparate Views

Visual place recognition methods which use image matching techniques have shown success in recent years, however their reliance on local features restricts their use to images which are visually similar and which overlap in viewpoint….

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…

Generic motion based object segmentation for assisted navigation

CASBliP – Computer Aided System for the Blind In the CASBliP project, a robust approach to annotating independently moving objects captured by head mounted stereo cameras that are worn by an ambulatory (and visually impaired)…

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…
