ABOUT ME

I obtained my BS degree in 2004 and defensed my PhD dissertation in 2008, both in National Taiwan University. My PhD advisor is Prof. Homer H. Chen. My research interests include image/video processing, computer vision, and multimedia hardware architecture. I will serve the military from Oct. 2009 to Sept. 2010 (as a citizen's obligation). From Sept. to Oct. I am a visiting researcher at Communications and Multimedia Laboratory under Prof. Winston Hsu and Prof. Yung-Yu Chuang.

SELECTED PROJECTS (see the full publiation list here)

Mobile Panorama

Panoramic Imaging System for Camera Phones
Kari Pulli, Chia-Kai Liang, Marius Tico, Xianglin Wang, and Yingen Xiong

Proc. IEEE ICCE 2010.

 

This is one of the projects I've done in Nokia research center, Palo Alto. Before I left, the first version is shipped with Nokia N86 8MP, and the second version (with fast Poisson and better color blending) is almost done. [user result 1] [user result 2] [user result 3] [user result 4]

Automatic Tage Annotation for Landmarks

Social Media for Recognition

Learning Landmarks by Exploiting Social Media [pdf]

Chia-Kai Liang, Yu-Ting Hsieh, Tien-Jung Chuang, Yin Wang, Ming-Fang Weng, and Yung-Yu Chuang

Proc. MMM, 2010.

The main programmer left the school for startup in the middle of the project :( ...still I'm pretty excited about the concepts and some preliminary results. I hope I will return to this topic in the future.
Also, all the best luck to the startup company of our programmer: http://fafafa.cc/ :)

Working with hardware people is a wonderful experience :). They initialize the problem, I deliver the algorithms (on GPU and GPU), and they do the rest (a REAL chip!). My contributions are presented in [CVPR'09]. The chip-level design and anaysis are given in [ICASSP'09] and future publications.
