Williem

Hi, I am Williem, a CTO and Cofounder of Verihubs, since June 2019. I obtained my Ph.D. degree in information and communication engineering from Inha University, Korea, in August 2017.

My research problem focuses on computer vision, computational photography, and image processing, which are as follows but not limited to:

Stereo matching
Light field depth Estimation
Light field synthesis
Image enhancement
GPGPU computation
SLAM
Face recognition
License plate recognition
License plate detection
