Some History

I gained the B.Sc. degree in Computer Science and Microprocessor Systems in 1984 from Strathclyde University, Glasgow, and the Ph.D. degree in Information Engineering from City University, London in 1988. I was a research fellow at City University, developing a prototype system for the Home Office to detect and classify intruders in image sequences. I worked on the Alvey project "Model-Based Interpretation of Radiological Images" at Guy's Hospital, London before becoming a lecturer at the Department of Computer Science, Curtin University of Technology, Perth, Australia. I moved Italy to work at the Institute for Remote Sensing Applications at the Joint Research Centre. followed by a return to the UK, becoming lecturer at the Department of Information Systems and Computing, Brunel University, London, UK. At the beginning of 2000 I moved to the School of Computer Science & Informatics, Cardiff University.

Research Interests

I am a member of the Departmental Geometric Computing and Computer Vision research group. See also this page for more details of the group's activities. We are also part of the Research Institute of Visual Computing. My past and present research has included:

extracting natural scales of curves	extracting corner properties	salience distance transforms	performance evaluation	thresholding for change detection	fitting ellipses and superellipses
shape analysis	facial analysis/synthesis	cellular automata for image processing	art and architecture	analysis of diatoms and desmids	content-based image retrieval
mesh filtering	reverse engineering of 3D reliefs	machine vision for remote sensing	non-photorealistic rendering

For a number of years I was newsletter editor and then secretary of the British Machine Vision Association.

	British Machine Vision Conference The British Machine Vision Conference (BMVC2002) was held in Cardiff in 2002! You can read about some of the work described at the conference in an article in HERO
	Agent based Computer Vision I was co-guest editor of the 2004 special issue of Pattern Recognition on Agent based Computer Vision. This was the original call for papers.
	Neural-Fuzzy Applications in Computer Vision I was co-guest editor of the 2000 special issue of the Journal of Intelligent and Robotic Systems on Neural-Fuzzy Applications in Computer Vision. This was the editorial, setting the scene.
	Machine Vision using Neural Networks I was co-guest editor of the 1998 special issue of Neural Computing and Applications on Machine Vision using Neural Networks.

I have organised some of the BMVA technical meetings. You can read the abstracts for Low Level Feature Extraction and AI Methods and Data Fusion in Remote Sensing Image Processing .

Software

Some software that I have developed (some of it in collaboration with colleagues) is available for:

approximating curves by lines and arcs
multi-scale segmentation and matching of curves using codons
automatic scale selection for curve smoothing
fitting superellipses
automatic thresholding of edges
salience distance transform
unimodal thresholding for edge maps and many other types of image
salient region detection
mesh filtering
computing convexity and rectilinearity shape measures

Demos

You can upload your images and try out our non-photorealistic rendering method for generating line drawings.

Images

The images used in the paper "An alternative approach to computing shape orientation with an application to compound shapes", Jovisa Zunic and Paul L. Rosin, International Journal of Computer Vision, vol. 81, no. 2, pp. 138-154, 2009 are available here.

Publications

You can see a list of my papers with many PDF files available too:

Teaching

This semester I am teaching CM0311 - Image Processing.
