| Abstract(in English) | We have been working on a marker-less motion capture system that works in a multiple camera environment. This system assumes 3D voxel data to be the input, while discrete human posture data is assumed to be the output. The discreteness of human posture data is provided by an example-based approach, which constructs human posture candidates from a large motion capture database beforehand. During the estimation process, the most appropriate candidate will be chosen through a simple similarity calculation between voxel data and posture candidates. This approach will drastically reduce the computational cost. compared to conventional methods, but increase of candidates will possibly lead to considerable computational cost. Therefore, prior to the similarity calculation phase, we introduce a near-neighbor search metric, which drastically decreases the similarity caculation frequency and the total computational cost. In this paper, we present a novel near-neighbor search metric, which is capable of dealing with much more candidates than the metric presented before, and yet maintaining the speed needed for online processing. |
