Abstract
In a video processing method, a video frame sequence comprising a moving target is obtained. According to the video frame sequence and by processing circuitry of a neural network model, a motion state feature representing the moving target is obtained. The motion state feature is expressed in a time sequence of the video frame sequence. A result of matching between the motion state feature of the moving target and a motion state feature of a designated target is obtained. The moving target is determined as the designated target in response to a similarity between the motion state feature of the moving target and the motion state feature of the designated target being greater than a threshold. According to the motion state feature of the moving target and by using a classifier, a probability that the moving target pertains to an action category corresponding to the designated target is obtained.
