“Hsieh Hsuan at the Dept. of CSIE, National Figure Skate”r, Develops an Action Analysis System for Figure Skating Hsieh Hsuan and Wu Ping-Hung, senior students at the Byinputtingvideosoffigureskatingjumps,the“Figure Department of Computer Science & Information Engi- neering (CSIE) in NCU, under the supervision of Profes- sor Chou Li-Der, developed the“Figure Skating Action Analysis System,”which was the very first software for automated analysis of figure skating jumps in Taiwan. The system also won the silver prize for smart machin- ery in the National Intercollegiate Contest for Smart Innovation and Cross-domain Integration. This automated motion analysis software can greatly assist figure skaters in reviewing and adjusting their jump performances. Hsieh Hsuan is a rare case in Taiwan, a talented student with knowledge of information engineering and figure skating. In , she represented Taiwan to compete at the Asian Open Figure Skating Trophy organized by the International Skating Union (ISU) and won the bronze medal. After she enrolled in the CSIE at NCU, she perfectly integrated her enthusiasm for and profes- sional knowledge of figure skating with programming skills, developing this action analysis system and providing amateur and professional figure skaters with a better learning tool. Skating Action Analysis System”can generate images of a limb skeleton. The system applies the Long Short-Term Memory (LSTM) model to recognizing and analyzing types of skating jumps, rotations in the air, fails, the takeoff foot, and the takeoff edge. In addition, based on the analytical results, the system further generates audio descriptions for the jumps and motions. Hsieh Hsuan and Wu Ping-Hung have spent one year watching numerous videos of international figure skating contests, retrieving up to precious video clips of skating jumps, and proceeding with the automated motion analysis. The system supports anal- ysis of all types of figure skating jumps, including the Axel, Loop, Flip, Salchow, Toe Loop, and Lutz jumps. With this motion analysis system that provides more precise data on skating moves and jumps, figure skat- ers can review their movements, improve their skating skills, and give brilliant performances to the audience.
