Method and device for gesture recognition

A device for gesture recognition, comprising a processor, a memory and an image sensor;

• wherein the processor executes programs stored in the memory to perform:
• acquiring an image of a user;
• detecting whether the image includes a human face;
• and
• performing gesture recognition based on information of the human face in response to detecting that the image includes the human face;
• wherein the performing of the gesture recognition based on the information of the human face comprises:
• dividing a first region including the human face from the image;
• dividing another region except the first region into a plurality of detection regions;
• determining respective priority levels of the plurality of detection regions;
• and
• performing sequentially the gesture recognition in the plurality of detection regions in an order from a high priority level to a low priority level.
