Title:
BEHAVIOR RECOGNITION METHOD AND DEVICE, AND COMPUTER STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/179591
Kind Code:
A1
Abstract:
Disclosed in embodiments of the present disclosure are a behavior recognition method and device and a computer storage medium. The method comprises: acquiring an image to be identified, and inputting said image into a pre-trained neural network; obtaining outputs of the neural network, the outputs comprising a first output representing the probability that the behavior of a character is normal in the image, a second output representing the probability that the character is performing a first behavior, and a third output representing the probability that the character is performing a second behavior; and determining the behavior of the character according to the outputs. Hence, according to the embodiments of the present invention, the behavior of the character in the image may be determined by using the pre-trained neural network, and specifically, the neural network may extract rich visual features and may pay attention to the specific behavior of the character in the image, so that the accuracy of behavior identification is higher. Moreover, the behavior recognition method provided in the embodiments of the present invention may meet an instantaneity requirement, and may perform real-time operation, thereby meeting the recognition requirements of various different application fields.
