Time sequence action detection is an important and challenging video understanding task. The task aims at reasoning the starting position, the ending position and the action type of an action instance in an unpruned long video. Most models with excellent performance at present are of an anchor-base category. A method of an Anchor-base category seriously depends on the size and the number of predefined anchors. In another type of anchor-free methods, most of the methods need additional classification models, so that the models cannot share information end to end. Due to the problems, an existing time sequence action positioning model is not flexible enough, and a large number of redundant parameters are generated. In order to solve the above problem, the invention provides an end-to-end anchor-free time sequence action detection method based on global information, and the method comprises the steps: carrying out the pre-training of a backbone network through employing a video data set kinetics ...
