I am a Ph.D candidate in EE department, KAIST. My major interests are computational photography which exploits visible & near IR cameras. Also, 3D computer visions; Shape from shding method for shape estimation, depth enhancement with photometric cues. I enjoy discussing about various kinds of computer vision research issues with research scientists. Feel free to contact me anytime you want. [Curriculum Vitae] [Google Scholar] [LinkedIn]
