Who am I?

Hi I’m Yang Liu (刘阳)! Currently, I’m a Ph.D. student in Singal Processing, where I closely collaborated with Dr Wenwu Wang and Prof Jonathon Chambers. My research area is audio-visual multi-speaker tracking with PHD filter and particle flow.

NOTE I have a poster in the ICASSP conference on15 May. I am in the shortlist for the "Best Student Paper Award". The poster link and my demo are shown below.

Demo: Watch Online

Speech script: Coming Soon

Code: Coming Soon

I will graduate in Autumn, 2019 and am looking for the internship and job now. My email address: yangliu@surrey.ac.uk. Please feel free to send an email to me!
