In this paper, we propose a model-based alignment system using real-coded genetic algorithm (RGA) for mixed reality (MR) or augmented reality (AR). MR/AR is a technique for superimposing useful virtual information on the real world to provide users more effective views. To realize the MR/AR, the alignment between real space and virtual space is a serious problem. In particular, an initial frame alignment...
In this paper, a method for hand posture recognition, which is robust for hand posture changing in an actual environment, is proposed. Conventionally, a data glove device and a 3D scanner have been used for the feature extraction of hand shape. However, the performance of each approach is affected by hand posture changing. Therefore, this paper proposes the posture fluctuation model for efficient...
We propose a method for real time estimation of head poses and facial expressions without using a complex 3D head model. Most conventional methods for head pose and facial expression estimation required preliminary estimation using a complex 3D head model. In the proposed method, however, a large number of feature points and a whole facial image are not required in order to estimate facial expressions...
