Wei-Chih Tu

I am a PhD student at National Taiwan University working with Prof. Shao-Yi Chien. I'm interested in efficient and robust solutions to vision problems. Recently, my research interests focus on learning better representations for low-level image processing.

I've been lucky to be an intern with Visual Computing Group at NVidia Research. I also worked with Dr. Qingxiong Yang as a visiting research assistant at CityU of Hong Kong.
