Hi Folks.
Tim here, lurking in the Imaging Science and Biomedical Engineering Research Group, University of Manchester, where I have worked since 1991.
I became a Professor of Computer Vision in August 2006.

Research Interests

I've had a great deal of fun developing statistical models of both shape and appearance, which have proved very useful for interpretting images of many different kinds. They are used in `Active Shape Models' (ASMs) and `Active Appearance Models' (AAMs) which iteratively deform to fit to image data. We've used them for locating bones and organs in medical images, for face and gesture recognition and for industrial inspection.
I'm also working on corresponding sets of shapes/images so as to find optimal shape/appearance models.
In the case of shapes, this involves finding sets of corresponding points across the group of shapes, which can then be used to build compact shape models.
In the case of images, we are developing methods of finding the diffeomorphisms (smooth, invertible mappings) between the images, effectively corresponding them. This work involves combining ideas from the statistical model building literature with those from the non-rigid medical image registration literature.

Descriptions of Research

The most comprehensive description of my research is given in this report (PDF, 120 pages, Updated Oct 2001).
This contains a detailed description of all our work on statistical models of shape and appearance, and is the best place to get details of the algorithms.

An overview of Flexible Models.
An overview of Point Distribution Models.
An overview of Active Shape Models.
An overview of Combined Appearance Models.
An overview of Active Appearance Models.
An overview of View-Based Appearance Models
An example of Tracking with View-Based Appearance Models.

A 15 page overview paper about ASMs and AAMs (a useful introduction) (PDF)
A more detailed (26 page) introduction to statistical shape models and ASMs (pdf)

I've started compiling timelines of key papers and developments in a few areas, to make it easier to discover who did what, and when. They're not yet completed, and any feedback will be appreciated.

Projects

I am involved in a number of projects, including:

Recently completed projects include:

Software

I write software predominantly in C++ using the excellent VXL computer vision libraries, to which I and my colleagues regularly contribute.
You can download VXL from Sourceforge.

A variety of software tools are now available here.

Datasets

You can find a range of useful annotated datasets on the FGNET Website.
Manual annotation of the BioID face images.
Manual annotation of the XM2VTS face images.
Manual annotation of the AR Face Database face images.
Images with annotation of a talking face.
A set of hand points.

Students

Steve Adeshina has recently started his PhD.
Some other groups using ASMs/AAMs or doing related work.

Lecture Notes, Documentation, Reports etc

Up until the end of 2000 I was funded by an EPSRC Advanced Fellowship. Thanks Folks.
