University of Oxford researchers have developed a novel system for robust, real-time tracking of objects in digital image sequences.

The Oxford Invention

Researchers at the Active Vision Group have devised a novel technique for robust, real-time, visual tracking. It can identify and track new objects in any video sequence, real-time or recorded and regardless of rapid and agile object motion, image blur, varying lighting, camera motion or cluttered and changing backgrounds.

The system presents distinct advantages over existing ones:

  • It requires minimal knowledge about the target's shape/appearance but does allow for shape or appearance constraints to be implemented, i.e. it can be set to ignore specific objects or specifically focussing on others;
  • It can track targets who appearance changes over time, for example a pulsating heart, spreading fingers, a turning ship or a running animal;
  • It is capable of tracking multiple targets at once within a single video image sequence;
  • It is supported by real-time implementation;
  • It can handle large inter-frame displacements, i.e. can cope with low video frame rates or fast moving objects;
  • It requires only a low degree of computational overhead and is suitable for portable and mobile applications.

Market

Visual tracking of objects has a wide scope of applications, some examples are surveillance (either terrestrial or maritime), medical imagery (identification of organs), gaming and smart user interfaces (tracking hand\body motions of users) and factory based quality control (tracking product movements on conveyor belts).

Patent Status

The Oxford invention is the subject of a patent application. Isis would like to talk to companies interested in developing the commercial opportunity. Please contact the Isis Project Manager.
