| Abstract(in English) | In a motion capture system (MCS) using multi-viewpoint images, it is effective to segment human area into each person when we estimate poses of two people. There are two approaches to segment the human area; one is using 2D image and the other is using 3D shape reconstructed from multi-viewpoint images. We have employed the approach to use the 3D shape which is represented in voxels. The main issue is to give each voxel a proper label which identifies the person. When a person does not touch another, it is easy to give a label by finding connected voxels. Otherwise, we have to find a boundary between the two. Therefore we define an energy function that express which label to be given for each voxel. We can get good segmentation result by minimizing the energy function based on a graph cut algorithm. |
