Research Interests

Build a hi-resolution 3D face model from a single low-resolution (2D) face image.  Using a portable computer (e.g., PDA), synthesize possible changes (facial hair, hair style, expressions, etc.) in the face's appearance.

Utilize the flexibility of DBNs in having hidden data and various conditional independencies so as to model additional information more easily than with traditional hidden Markov models (HMMs).

Incorporate auxiliary information (energy, rate-of-speech, pitch, articulators) into speech recognition to make it more robust in noisy conditions.
