3D Environmental Modeling

This project is to generate 3D environment maps that Robot enables to navigate the 3D world. Limited views of range finders needs to merge several range data into one connected maps. We are developing an improved registration method.

3D Object Recognition

3D object recognition is challenging problem. We are focusing on affine invariant and illumination invariant methods to make the algorithm more accurate.

Reflectance Analysis and Synthesis

Under projector-camera based illumination environment, we try to analyze specular and diffuse components of objects. Without geometry information, we estimate surface characteristics.
People : Hyunju Kim, Sang Wook Lee




Omni-directional Vision

Mirrors can expand the limitation of field-of-view of camera. We capture images including various shape of mirror to get omni directional information. Our goal is to get 3D geometry around mirrors and a camera.

Real-time 3D Geometry

Real time 3D capture technique enable to generated 3D data of animated objects with complex motion. We use color stripe patterns to identify each position of projection with one image. We are also focusing on getting correspondent between obtained 3D geometry data.

Human Skin Color and Texture

Skin has translucent and glossy reflectance characteristics. If we obtain these characteristics, we can render more realistic skin in applications of Computer Graphics. We use data-driven approach to include all the reflectance information including translucent, glossy, and texture.

Marker-Free Facial Motion Capture

Without makers to get correspondence between frames, we try to get dense motion data of face. Improved pattern enable to get face geometry in real time. We can transfer not only sparse sets of motion vectors but also dense clouds of motion information onto new 3D face model.

Image based Illumination of Artistic Paintings

Instead of taking photos of painting for digital display, we analyze the illumination characterics of each paintings such as oil, pastel, water, and acryl color paintings. we can synthesize the realistic appearance of paintings under various lighting conditions.
