The research goal of POSTECH Computer Graphics Lab is to investigate on principles, algorithms, and applications of various subjects in graphics and related areas. The current research topics include image and video processing, non-photorealistic rendering, surface reconstruction, and mesh processing. In image and video processing, we work on motion deblurring, image upsampling, video retargeting, and texture filtering, to provide tools for processing photographs for more desirable results. Non-photorealistic rendering targets to create expressive, artistic, and interpretative images of objects rather than photo-realistic images. In surface reconstruction, we focus on statistical techniques that can handle noise and outliers of 3D scanned point sets. In mesh processing, we develop techniques to effectively handle large and animation polygonal meshes. We are also interested in industrial applications of our expertise, such as web/mobile applications and Photoshop plug-ins for motion deblurring and image stylization.
