Hi there, Welcome to my
homepage
I am an academic staff with the Research School of Engineering,
CECS (
In 2009 I
was a Senior Researcher with NICTA (National ICT Australia) and also an Adjunct
Fellow with RSISE ANU. Prior to
2009 I was a Fellow and Research Fellow with the
My main research interests are Computer
Vision, Image and Video Processing, Pattern Recognition and Visual Geometry.
|
I am doing both research, teaching, and PhD supervision on Computer Vision @ RSISE where I have the great privilege to be working with Professor Richard Hartley --- the pioneer and leader in Geometric Computer Vision and Multiview Geometry. For future PhD students: If you want to persue PhD or Master degree in Computer
Vision, Image Processing, Computer Graphics and CAD/Animation, or
Pattern Recognition (incl. machine learning) from ANU or NICTA, please
email me for a discussion (though your
formal application must be lodged through ANU’s
official website). For scholarships, you have many
choices, such as IPRS, APA, ANU
scholarship and NICTA schohlarship, etc.
Note: ANU's application dead line is 30st August (for
international students) every year, and 30 October (for domestic and |
