Chang Wook Seo

I am a PhD candidates at KAIST (Korea Advanced Institute of Science and Technology), Culuture Technology advised by Junyong Noh.

Master of Science at Sogang University, Media Technology, advised by Yongduek Seo. Bachelor of Fine Arts at Kyoto University of Arts.

Before starting my research career as a computer scientist from master's course, I was a 3D artist at Donuts Co. Ltd. I've worked on game develop team Warship Craft.

Paper

We proposed line art auto-colorization model which enhances its performance by using a few segmented image data.

Project

In project, I've developed many different kinds of applications based on deep learning. Mesh reconstruction, image recognition, image manipulation, video generation, video captioning and more.
Moreover, I also have the experience of creating 3D resources for mobile game as a 3D artist.

	KOCCA: 3D Fashion avatar reconstruction for metaverse June 2023 ~ Present I'm developing the AI model for 3d human reconstruction. Additionally researching on fashion image manipulation techniques.
	NIA: Construct dataset for video captioning June 2023 ~ Present I'm developing the AI model for video captioning.
	Samsung Research: Future project June 2022 ~ Dec 2022 I developed new video generation techniques for future project.
	IITP: Cinemagraph AR/VR project Mar 2021 ~ Dec 2022 I developed scene mesh reconstruction method for VR devices. Additionally researched 3D human generation based on a single image.
	Hyundai Mnsoft: SD map road status generation Mar 2019 ~ Dec 2019 I developed image classification method for traffic sign plate Additionally researched OCR (Optical Character Recognition) method for recognizing traffic sign plate (Korean)
	Game: 艦つく -Warship Craft- Apr 2017 ~ Jan 2019 I created 3D modeling and animation resources of the mobile game. Additionally developed in-house tool of MAYA and Unity shader.
