1. IntroductionIn recent years, human action recognition has become a research hotspot with a wide range of applications. For example, in the field of medical monitoring [1], human action recognition can provide real-time monitoring, alerting doctors or family members when necessary. In the gaming domain of human–computer interactions [2], human action recognition can be used to respond more intelligently to the player’s actions.
