Abstract(in English) | A novel head gesture recognition system for conversation robots is realized, which works well even with distorted input images caused by the movements of the robots. It is very important for the conversational robot to recognize head gestures of conversational partner, because they play important role to realize smooth communication. In this study, we firstly investigate a base system of gesture spotting, which uses HMM and optical flow-based feature extraction. This base system works well when the robot is inactive. However, the performance is degraded when the robot itself is performing gestures since the input images are seriously distorted in this case. To solve this problem, a compensation method of feature parameters using optical flow of body area is proposed, and the MLLR model adaptation technique is adopted. Experimental results show the effectiveness of these techniques. |
