Abstract

The embodiment of the invention discloses an object recognition method and device, a network training method and device, equipment and a medium. The object recognition method comprises the following steps: acquiring a to-be-recognized video frame of which a picture comprises a target object; the to-be-identified video frame is any video frame in a video stream of the target object; determining an initial attitude sequence of the target object based on a to-be-recognized video frame and a historical video frame of the to-be-recognized video frame in the video stream; performing probability mapping on the initial attitude sequence to obtain a target attitude sequence of the target object in the to-be-identified video frame; performing feature conversion on the target attitude sequence in space and time to obtain an attitude feature track of the target object in the to-be-identified video frame; and determining a behavior state of the target object in the to-be-identified video frame based on the attitude feature trajectory.

Description

technical field [0001] The embodiments of the present application relate to the field of image processing, and in particular to an object recognition method, a network training method, a device, a device, and a medium. Background technique [0002] In related technologies, abnormal video frames are identified from video streams based on pixel methods such as optical flow or frame gradients, which are easily affected by noise in video images, resulting in poor recognition results. Contents of the invention [0003] An embodiment of the present application provides a technical solution for object recognition. [0004] The technical scheme of the embodiment of the application is realized in this way: [0005] An embodiment of the present application provides an object recognition method, the method comprising: [0006] The acquired picture includes a video frame to be identified of the target object; the video frame to be identified is any video frame in the video stream of...
