Résumé
After the COVID-19 pandemic, the importance of teleteaching using networks has been increasing in regular university classes. The authors have been studying on the improvement of athletic performance of college women's basketball as extracurricular activities using information processing from multi-image. In this paper, we propose the use of such a multi-visual system in basketball classes. In this experiment basketball athletes at the gymnasium gallery shooted play of other athletes on the court using smartphones. Furthermore, the effectiveness of this video is discussed in terms of regular university classes. One of the characteristics of this video information system, which was realized on the premise of the existing campus network, is that it is a highly feasible system that does not interfere with other lectures and the daily work of faculty members in the university. © 2021 IEEE.
