Behavior recognition method and apparatus, medium, and electronic device

A computer-readable storage medium, wherein the storage medium stores a computer program used to implement a behavior recognition method including:

• obtaining a sequence of image blocks containing a target part of a target object from a plurality of video frames obtained by a camera apparatus disposed in a mobile device;
• performing feature vector extraction that is based on a first preset behavior to the sequence of image blocks, to obtain a first feature vector corresponding to the sequence of image blocks;
• determining a behavior type to which a behavior of the target object belongs based on the first feature vector;
• and
• if the behavior type to which the behavior of the target object belongs satisfies a first behavior type, determining the behavior of the target object based on a result of performing behavior recognition on a second preset behavior for the sequence of image blocks.

An electronic device, wherein the electronic device includes:

• a processor;
• and
• a memory configured to store processor-executable instructions,
• wherein the processor is configured to read the executable instructions from the memory, and execute the instructions to implement a behavior recognition method including:
• obtaining a sequence of image blocks containing a target part of a target object from a plurality of video frames obtained by a camera apparatus disposed in a mobile device;
• performing feature vector extraction that is based on a first preset behavior to the sequence of image blocks, to obtain a first feature vector corresponding to the sequence of image blocks;
• determining a behavior type to which a behavior of the target object belongs based on the first feature vector;
• and
• if the behavior type to which the behavior of the target object belongs satisfies a first behavior type, determining the behavior of the target object based on a result of performing behavior recognition on a second preset behavior for the sequence of image blocks.
