Gesture recognition method, device and computer-readable storage medium

A gesture recognition device, comprising:

• one or more processors;
• a memory;
• and
• one or more programs, wherein the one or more programs are stored in the memory and configured to be executed by the one or more processors, the one or more programs comprise:
• instructions for acquiring a target image containing a gesture to be recognized;
• instructions for inputting the target image to a gesture recognition model that comprises a first sub-model, a second sub-model, and a third sub-model that are in a parallel relationship, the first sub-model configured to determine a gesture category and a gesture center point, the second sub-model configured to determine an offset of the gesture center point, and the third sub-model configured to determine a length and a width of a bounding box for the gesture to be recognized;
• instructions for acquiring an output result from the gesture recognition model, wherein the output result comprises the gesture category, the gesture center point, and the offset of the gesture center point, and the length and the width of the bounding box;
• and
• instructions for determining the gesture category and a position of the bounding box of the gesture to be recognized according to the output result.

A non-transitory computer-readable storage medium storing one or more programs to be executed in a gesture recognition device, the one or more programs, when being executed by one or more processors of the gesture recognition device, causing the gesture recognition device to perform processing comprising:

• acquiring a target image containing a gesture to be recognized;
• inputting the target image to a gesture recognition model that comprises a first sub-model, a second sub-model, and a third sub-model that are in a parallel relationship, the first sub-model configured to determine a gesture category and a gesture center point, the second sub-model configured to determine an offset of the gesture center point, and the third sub-model configured to determine a length and a width of a bounding box for the gesture to be recognized;
• acquiring an output result from the gesture recognition model, wherein the output result comprises the gesture category, the gesture center point, and the offset of the gesture center point, and the length and the width of the bounding box;
• and
• determining the gesture category and a position of the bounding box of the gesture to be recognized according to the output result.
