摘要：
Action recognition methods are disclosed. An embodiment of the methods includes: identifying a video that comprises images of a human body to be processed； identifying at least one image to be processed, wherein the at least one image is at least one of an optical flow image generated based on a plurality of frames of images in the video, or a composite image of one or more frames of images in the video； performing convolution on the at least one image to obtain a plurality of eigenvectors, wherein the plurality of eigenvectors indicate a plurality of features of different locations in the at least one image； determining a weight coefficient set of each of a plurality of human joints of the human body based on the plurality of eigenvectors, wherein the weight coefficient set comprises a weight coefficient of each of the plurality of eigenvectors for the human joint； weighting the plurality of eigenvectors based on the weight coefficient set to obtain an action feature of each of the plurality of human joints； determining an action feature of the human body based on the action feature of each of the human joints； and determining an action type of the human body based on the action feature of the human body.
