A major challenge in neuroscience research is detecting and characterizing changes in brain structure. A PhD scholarship is available in the Faculty of Medicine and the Faculty of Engineering at Monash University to develop novel image analysis and statistical techniques for examining the structure of the brain of humans and animal models. This work will contribute to the success of leading edge neuroscience initiatives such as the Australian Mouse Brain Mapping Consortium.

This project combines Bayesian filtering theory with stochastic geometry to address the problem of tracking multiple-object tracking in video sequences. The Bayesian framework is employed for its suitability to on-line implementation and its adaptability to the fusion of heterogeneous sources of information. The stochastic geometric modelling provides a solid foundation for the systematic study of the problem and allows principled approximations to made. Stochastic geometrical models, including deformable templates and point processes have long been used by statisticians to develop techniques for object recognition in static images [24]. However, their use has been largely overlooked in the tracking area until recently. In tracking with point measurements, an approximation based on point process theory known as the Probability Hypothesis Density (PHD) filter has been shown to alleviate the data association problem and remove the bulk of the computational load [25-28]. In this project we will develop a PHD-type filter for video data to arrive at an efficient algorithm for tracking multiple objects.

Postoctoral Position and PhD Scholarship in Robust Statistical Fitting

Our aim is to study the essential (and ubiquitous) problem of automatically segmenting visual data into meaningful parts - a form of model fitting: but in the face of multiple objects, missing and noisy data, large data volumes, and unknown form (model) and number of objects. These latter characteristics lift the problem beyond the reach of standard statistical fitting approaches.
There have been studies concentrating on optimal fitting (Kanatani 1996) (ignoring such things as outliers, multiple structures, data sample density etc.), or on robust fitting in the presence of multiple structures ((Meer 2004) not only provides a good overview if these approaches but also a good discussion of why traditional robust statistics is inadequate for such a setting) but generally ignoring small sample issues, model selection, and a plethora of other practical issues. This project is an ambitious attempt to provide a more complete theory and practical methodology.
The project will focus on range data (i.e., laser scan and 3D reconstruction from images) and motion estimation/segmentation. It will build upon the work of the team (see references below).

UK PhD/Master by research scholarships for International Students

As per request from saoirse, I decided to do a quick search on UK's scholarship opportunities. Similar to many other countries, they've got fundings to cover both the course fees and livings. For eg, in Warwick Uni:

Warwick Postgraduate Research Scholarship
The Warwick Postgraduate Research Scholarship is a prestigious programme of awards for PhD students run by the Warwick Graduate School. The award scheme is run on a competitive basis and competition for the awards is keen.

If you are a high calibre candidate in any discipline with a proven academic track record and the potential to be an outstanding researcher in your field, we would welcome an application from you. Warwick Postgraduate Research Fellowships offer:

The payment of your academic fees at the Home/EU rate
A combined salary and maintenance grant of £13,000 (for full-time award holders in 2006/2007)
(roughly the same rate as livings provided in Australia, Singapore, Japan and US)
The opportunity to gain valuable work experience within your academic department

You can apply to hold an award in any department at the University of Warwick. The scheme is open to UK, EU and overseas students. Applicants for a Warwick Postgraduate Research Fellowship are required to apply for alternative funding, for example UK and EU students should apply to the UK Research Councils and overseas students to the Overseas Research Studentship Competition.

For more information about funding your Postgraduate Research, visit the Student Funding website
You should note that before you apply for the funding you should already have applied online to study the MPhil/PhD or PhD via the following link:
http://www2.warwick.ac.uk/study/postgraduate/
If you have any queries please do not hesitate to contact the Student Records Team by email on
studentrecords@warwick.ac.uk
Taken from http://www2.warwick.ac.uk/study/postgraduate/funding/

There are a few more scholarships for overseas student:

University of Warwick Awards for International Students
The University offers awards for students in various countries and also participates in jointly funded scholarship schemes. Full details are available on the International Office website or email the International Office at Int.Office@warwick.ac.uk

Foreign and Commonwealth Office British Chevening Awards
The application process is organised by the British Council, British Embassy or High Commission in your home country. Information is also available on the Foreign and Commonwealth Office website.

Commonwealth Scholarships and Fellowship Programme
Commonwealth scholarships are available for candidates in Commonwealth countries or British dependent territories who qualify for postgraduate study (taught courses and research degrees). Further details are available from the Ministry of Education in your home country and on the Association of Commonwealth Universities website.

Overseas Research Student Awards Scheme
This scheme is open to overseas applicants who want to follow a postgraduate research degree in the UK. The scheme pays the difference between the home and overseas fees for full-time students of outstanding merit and research potential. You must hold an offer from the University to study for a MPhil/PhD or PhD before applying for an ORSAS award. Application forms and further information for awards starting in September 2006 can be found at http://www2.warwick.ac.uk/academicoffice/postgrad.

Commonwealth Shared Scholarship Scheme (formerly DFID Shared Scholarship Scheme)
These scholarships are funded by the Department for International Development and British Universities. The scheme is intended to help students from developing commonwealth countries to follow postgraduate courses related to the economic and social development of their home country. Awards are available for specific taught Masters degrees. Departments nominate candidates for these awards so please indicate that you wish to be considered for a DFID award on your application form. The DFID application form will be available on our website from January 2006. Further information is available from DFID’s website or the Scholarships Officer in the Graduate School. E-mail studentrecords@warwick.ac.uk


Also taken from the page mentioned. For other unis in UK, I would expect similar scholarship opportunities exist =)

So good luck to those applying, and don't forget the deadline: 30th March 2007
*generally, you could contact the *proposed* supervisor to discuss for research topic before applying for the scholarship.

Oh and just a reminder - the deadlines for most Australia's research scholarship is on 31thOct2007 - don't miss out if you are interested!
