Computational Geometry and Graphics Lab
Machine-translated · View original
A lab that edits and generates images of people and terrain using computer graphics and image processing.
AboutAbout the lab
Handling diverse subjects with CG and image processing.
The Computational Geometry and Graphics Lab conducts research on diverse subjects such as people, terrain, and fonts, centered on computer graphics (CG) and image processing.
The lab works on technologies for editing and generating clothing, age, pose, body shape, makeup, and more in images of people, as well as on generating and editing terrain landscapes using weather satellite data.
It also pursues research that deals with the subjective evaluation of beauty, such as image editing that improves the aesthetics (how good a photo looks) of photographs.
The lab actively encourages presenting research outside the university, and supports undergraduates in learning through conference presentations in Japan and graduate students through conference presentations abroad.
Key terms
- Computer graphics (CG)
- Technology that uses computers to create and process images and video
- Aesthetics
- How good a photo or similar image looks. An evaluation of beauty, which people feel differently
- Relighting
- Editing that changes, after the fact, how light falls on the people or objects in a captured image

ResearchResearch themes
This lab works on research dealing with diverse subjects such as people, terrain, and fonts, centered on CG and image processing. It conducts research aiming to contribute to the fields of computational geometry and CG.
*Illustrative imageEditing and generating images of people
The lab studies technologies that freely manipulate the appearance of people, such as changing clothing from text instructions, editing age, expression, pose, body shape, and makeup, and relighting. It also has research on generating images of a person from an arbitrary viewpoint from images taken from multiple viewpoints.
*Illustrative imageGenerating and editing terrain landscapes
Using weather satellite data and other sources, the lab researches the creation of realistic terrain landscapes, including technology that simultaneously generates terrain shape and texture, and season-dependent texture control.
*Illustrative imageEditing to improve how photos look
The lab pursues research that deals with the subjective evaluation of beauty, such as technology that improves the aesthetics (how good a photo looks) of photographs by manipulating the camera viewpoint.
*Illustrative imageRelated research in CG and image processing
The lab also works on font image synthesis in which use cases such as brand logos can be specified, building a large-scale dataset of illustration face landmarks, and automatic generation of reflection probes.
