Giljoo Nam

I am a PhD student at Visual Computing Lab, KAIST, under the supervision of Prof. Min H. Kim.

My research lies in the field of Computer Vision and Graphics. I am interested in inferring and recovering the real world information from captured images. My current research focuses on developing systems and methods to acquire the full 3D geometry of an object and its reflectance for hyper-realistic appearance rendering in virtual reality and augmented reality. For detailed information, find my CV [here].

* Currently, I am doing my internship at Facebook Reality Labs in Pittsburgh, PA (July 2018 - Dec 2018).
