Digital Image & Geometry Processing

Research Subjects and Results

I have been working on processing shape via computer and have developed the new and efficient computational methods for digital image and geometry processing. Particularly, I have proposed the fast and robust methods for real-world data via computer. The developed methods include the fair shape generation [SMI'99,GMP'02], geometric mesh deformation []PG'02,SMA'03,EG'07], smoothing and noise reduction [SMI'06,CGF'10], feature extraction and analysis [SMI'01,MMM'00,SPM'05,PG'07,CAGD'08,ICGG'10], and mesh parameterization and remeshing [SMI'04,IJSM'05].
Also the applications to registration [ISDA'09,IJCIA'10], noise reduction [ICSB'10], and feature extraction [ViEW'10] of the biomedical 3D images obtained by CT, MRI, or confocal laser scanning microscopes have been studied.

Future Target

I will work on proposing the new methods for processing digital image and geometry, and develop the application systems based on the proposed methods.
