Geometric Algebra |
|
|
Geometric Algebra (GA) is a mathematical framework based on the algebra of William Kingdon Clifford. It works with scalars, vectors, bivectors (oriented areas), trivectos (oriented volumes) etc., and provides us with an algebra which is capable of manipulating all of these quantities in one system. One of the major advantages of GA is the ease with which it deals with rotations, of any quantity and in any dimension. The Signal Processing Geometric Algebra research page gives details of past and current projects, publications, collaborations etc and can be found here |

Structured Light Plethysmography |
|
|
Structured Light Plethysmography (SLP) is a non-invasive technique for measuring lung function in humans and animals. We employ a multiple camera system and a projector to dynamically reconstruct the moving surface of the chest and abdomen via features extracted from structured light. The Signal Processing SLP research page gives details of past and current projects, publications, collaborations etc and can be found here |

Inertial Navigation |
|
|
This project [Liam Candy, PhD topic] explores a Geometric Algebra approach to the inertial navigation problem. Firstly the 3D equations are rewritten to express the attidtude computations in terms of bivectors and then this is extended to 5D to incorporate both attitude and position. More details of this project can be found here |

Gait and Rehabilitation |
|
|
The Signal Processing Group collaborates with Dr Adar Pelah on a number of gait/rehabilitation related projects. These involve investigating the interactions of humans in virtual environments with a view to providing real-time visual feedback for a number of activities. More details of these projects can be found here |
