Body contour key point detection methods, apparatuses, and devices

An electronic device, comprising:

• a processor;
• and
• a memory for storing instructions executable by the processor;
• wherein execution of the instructions by the processor causes the processor to perform:
• obtaining an image feature of an image block comprising a body;
• obtaining, by means of a first neural network, a body contour key point prediction result of the body according to the image feature;
• and
• obtaining, according to the body contour key point prediction result, a body contour key point in the image block, wherein the body contour key point is used for representing an outer contour of the body.

A non-transitory computer-readable storage medium, configured to store computer-readable instructions, wherein execution of the instructions by the processor causes the processor to perform:

• obtaining an image feature of an image block comprising a body;
• obtaining, by means of a first neural network, a body contour key point prediction result of the body according to the image feature;
• and
• obtaining, according to the body contour key point prediction result, a body contour key point in the image block, wherein the body contour key point is used for representing an outer contour of the body.
