Embodiment 1
[0031] figure 2 It is a flow chart showing a key point detection method according to Embodiment 1 of the present invention.
[0032] refer to figure 2 , in step S210, video optical flow data is acquired according to the first video frame and the second video frame included in the video sequence, and the video optical flow data is used to indicate the displacement data of each pixel between the second video frame and the first video frame. Wherein, the second video frame includes at least one video frame that is sequential in sequence and located before the first video frame in the video sequence.
[0033] Among them, the video sequence may include but not limited to live video, recorded video, human-computer interaction video, game video, surveillance video and so on. The first video frame and the second video frame are continuous video frame images in the same video content, and each of the first video frame and the second video frame includes a plurality of pixels and in...
Embodiment 2
[0044] image 3 It is a flow chart showing a key point detection method according to Embodiment 2 of the present invention.
[0045] refer to image 3 , in step S310, video optical flow data is acquired according to the first video frame and the second video frame through a deep neural network for generating video optical flow data.
[0046] In this embodiment, when the key point detection of the target object is performed on the continuous video frames of the video sequence, the continuous second video frame and the first video frame are processed by a deep neural network for generating video optical flow data, thereby obtaining the video The optical flow data indicates the displacement data of each pixel between the second video frame and the first video frame.
[0047] When performing this step, by inputting the second video frame and the first video frame into the trained deep neural network, the video optical flow data between the second video frame output by the deep n...
Embodiment 3
[0066] Figure 4 is a logic block diagram showing a key point detection device according to Embodiment 3 of the present invention.
[0067] refer to Figure 4, the key point detection apparatus of this embodiment includes a first acquisition module 402 and a second acquisition module 404 . The first acquisition module 402 is configured to acquire video optical flow data according to the first video frame and the second video frame included in the video sequence, and the video optical flow data is used to indicate that between the second video frame and the first video frame Displacement data of each pixel, the second video frame includes at least one video frame in the video sequence that is sequential in time sequence and located before the first video frame. The second obtaining module 404 is configured to obtain the first key point of the target object in the first video frame according to the obtained second key point data of the target object in the second video frame a...
