Activity Analysis

Our research on activity analysis from video has focussed largely on human behaviour. We are interested in all aspects of this problem, including fundamental research on categorisation, tracking, segmentation and motion modelling, through to applied work addressing social and commercial priorities. Some of our recent work, in collaboration with the School's KRR group, is exploring the integration of vision within a broader cognitive framework, including audition, inductive reasoning, and intentionality.

[Detecting Carried Objects]

Relational Description of Video Scenes

Learn about the activities within a scene, and then about the objects involved in these activities

[Bicycle Theft Detection]

Bicycle theft detection

Recognising drop and pick events and linking related events applied to bicycles. This method could assist raising a warning when the person picking the bicycle does not 'look like' the person who dropped it

[Detecting Carried Objects]

Detecting carried objects

Detect large objects (e.g. bags) carried by pedestrians depicted in short video sequences

[Detecting Carried Objects]

Motion segmentation by consensus

Segment moving objects from tracked features

Learning to play table-top games

Learn about the objects and patterns of moves used in simple table-top games, and then apply these to play the game

[Image of intentional map]

Modelling the intentions of pedestrians

Detect atypical pedestrian trajectories, assuming a simple model of goal-directed navigational behaviour

Watermark extraction

Localise paper-based watermarks using image processing
