Pitching Motion Matching Based on Pose Similarity Using Dynamic Time Warping
Ryohei Osawa, Takaaki Ishikawa, Hiroshi Watanabe · 2020
By comparing multiple videos, it is possible to find the differences between the movements by different players or between motions of the same player in separate situations. To compare multiple motions, it is necessary to match the timing of the motions. However, it is difficult to synchronize the timing since the motion speed and usage of the body varying by player and situation. Therefore, in this paper, we propose a matching method for two pitching motions based on pose similarity using Dynamic Time Warping (DTW). This method enables accurate matching of two pitching motions in many cases.
