>>> Welcome to my homepage <<<

Hi, there, I now move to NICTA as Senior Researcher, working on VIsion processing for Bionic Eyes. The idea is to use advanced computer vision technologies to help the blind people to restore vision(sight). I am still an Adjunct Fellow (Senior Lecturer) of ANU.

For future students: If you want to persue an ANU PhD or Master degree in Computer Vision, Image Processing, Computer Graphics and CAD/Animation, and/or Pattern Recognition (incl. machine learning), please email me for discussion (though your formal appliction must through ANU admission office). For scholarships, you have many choices, such as IPRS, APA, ANU scholarship and NICTA schohlarship, etc.

Note: ANU's application dead line is 30 August (for international students) every year, and 30 October (for domestic and New Zealander students) each year, or 31 May (for mid-year entry).

My office is CRL Lv-31, Phone: +61 (2) 6267 6236.

I can be reached by emailing me : Hongdong.Li@anu.edu.au, or Hongdong.Li@Nicta.com.au;

Previously I was a Fellow at the Computer Vision Group, RSISE (Research School of Information Sciences and Engineering), Australian National University (ANU).

I was also a contributed Senior Researcher with NICTA (formerly National ICT Australia), Canberra Research Labs. NICTA is an Australian Government funded ICT research institute. At NICTA I am working on visual processing for the Bionic Eye project (VIBE).

I am doing both teaching/supervision and research on Computer Vision @ RSISE where I have the great privilege to be working with Professor Richard Hartley ---a pioneer and leader in geometric computer vision and multiview geometry.

My past research projects included Handwritten Characters Recognition and Mobile-Robot-Navigation. Recent research interests include:

------- Computer Vision, Multi-view geometry and Multi-camera system,

-------- Motion and Tracking.

------- Bionic-Eye, Visual Processing Unit for Retinal Prosthesis

------- 3D Modelling and 3D Reconstruction.

------- Image Processing, Image Restoration.

------- Pattern Recognition and Machine Learning.

------- Computer Graphics and Computer Geometry.

***************** SELECTED PUBLICATIONS *****************

In computer vision research, the major forums for publication are ICCV, ECCV, CVPR. The ICCV and ECCV have impact factor rankings by CiteSeer in the top 5% and 7%, respectively, of all computer science journals and conferences. In Australia and New Zealand, they are the top A* tier (viz. top 5%, by ANZSRC 2008) and A+ tier (viz. top 6%, by CORE 2006) publications.
