RETRACTED ARTICLE:Sea level height and swimmer’s physical training based on the detection of actors

Abstract

Actor detection means detecting intricate human activities in long videos that have never been edited. It is not only necessary to distinguish between its behavior and background categories, but also to predict the starting point and ending point of the agent's detection, that is, to create a time axis positioning. Therefore, the task can be divided into two stages: first create a candidate area that may generate behavior in the entire long video, and then classify the candidate area into background/behavior classification, and output precise positioning on the time axis to complete behavior detection. Sea level change refers to the phenomenon of sea level rise and fall. The factors that cause changes in sea level height are complex, which in turn affects the world. This article mainly studies the changes in regional sea level, that is, the changes in sea level along the coast of China. The influencing factors are more complicated. The physical training methods for swimmers mainly include the size of surface support, the number of support points, how to adjust the torque, and the physical links involved in completing the action. The concept of time is introduced, which will increase the body load of swimmers. But at the same time it can improve endurance and range of motion. Among them, physical training has always been one of the hot topics in the field of sports training in China. The physical training techniques in the swimming training process can not only improve the swimmer's special competition ability, but also prevent sports injuries and prolong the life of the swimmer.
