| Abstract;This paper describes a technique for recovering 3-D human motions from its single video image by a computer vision system. Several motion recovery techniques including stereoscopic vision exist as commercial products. They are, however, still not very convenient for widespread use because of camera calibration, the use of artificial markers attached on a human whose 3-D positions are to be tracked, etc. Unlike these existent techniques, the proposed technique employs neither camera calibration nor markers. Instead it employs a motion database that describes human motions. Once a motion is observed, the technique performs its 3-D recovery by retrieving a similar motion in the database. The database is created employing PCA (Principal Component Analysis), since it can reduce image information effectively as well as it performs less amount of image preprocessing than other methods employing the feature space. Some basic human motions are recovered successfully in the experiment performed. (author abst.) |
