Fig. Since 2003, Korea Government has been supporting a research on intelligent robotics (10 years, 130 million dollars) as one of 21C Frontier Programs. We are developing service robots who will be suppose to help elder peoples. Especially, our group (ISRC) is working on the topic "3D Object/Environment Recognition and Modeling for Manipulation." Based on our technology (sensing, modeling and recognition), T-bot can serve in the Robotic Cafe.

Fig. Facial image representations using (a) PCA, (b) ICA architecture I, (c) ICA architecture II, (d) proposed LS-ICA, (e) LNMF and (f) LFA basis images: A face is represented as a linear combination of basis images. The basis images were computed from a set of images randomly selected from the AR database. Using Proposed LS-ICA basis images, the concept of “recognition by parts” can be effectively implemented for face recognition.
