BEHAVIOR IDENTIFICATION METHOD, DEVICE AND COMPUTER-READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/042547
Kind Code:
A1
Abstract:
The present solution relates to artificial intelligence. Provided are a behavior identification method, a device and a storage medium. Said method comprises: segmenting a video stream into an image frame sequence; detecting a human body contour in each frame, and marking each human body with a first rectangular box; calculating the distance between any two first rectangular boxes in each frame; if the distance between two first rectangular boxes in a certain frame is less than a threshold, using a two-person combination box to enclose the two first rectangular boxes; searching a plurality of preceding and following frames, enclosing two persons which are the same as those in said two-person combination box to form a two-person combination box, and forming a two-person combination box sequence by using the two-person combination boxes in said frame and in the plurality of preceding and following frames; and inputting the two-person combination box sequence into a neural network model to perform behavior identification. The present application avoids a large amount of calculation of the neural network model caused by the unnecessary background, and also reserves features which are valuable for behavior determination between two persons, thereby improving the accuracy of behavior identification in a complex scenario.
