Image generation method and device

An electronic device, comprising

• at least one processor;
• and
• a memory storing at least one program that upon execution by the at least one processor, causes the electronic device to:
• acquire an image of a target moving object, wherein one or more limb parts of the target moving object are presented in the image;
• input the image to a pre-trained detection model to obtain an output result including a plurality of feature images for indicating position distribution of the one or more limb parts, presented in the image, in a preset limb part set, wherein the plurality of feature images includes a first feature image for a first limb part of the one or more limb parts, and a second feature image for a second limb part of the one or more limb parts, the first feature image and the second feature image having the same size as the image of the target moving object;
• generate one or more thermodynamic images corresponding to the one or more limb parts based on the plurality of feature images of the output result;
• and
• superimpose the one or more thermodynamic images to one or more regional positions, corresponding to the one or more limb parts, in the image of the target moving object to generate a superimposed image comprising the image superimposed with the one or more thermodynamic images,
• wherein the first feature image includes a first limb contour for the first limb part of the one or more limb parts, and the second feature image includes a second limb contour for the second limb part of the one or more limb parts.

A non-transitory computer-readable medium, storing a computer program to perform operations when the computer program is executed by a processor, the operations comprising:

• acquiring an image of a target moving object, wherein one or more limb parts of the target moving object are presented in the image;
• inputting the image to a pre-trained detection model to obtain an output result including a plurality of feature images for indicating position distribution of the one or more limb parts, presented in the image, in a preset limb part set, wherein the plurality of feature images includes a first feature image for a first limb part of the one or more limb parts, and a second feature image for a second limb part of the one or more limb parts, the first feature image and the second feature image having the same size as the image of the target moving object;
• generating one or more thermodynamic images corresponding to the one or more limb parts based on the plurality of feature images of the output result;
• and
• superimposing the one or more thermodynamic images to one or more regional positions, corresponding to the one or more limb parts, in the image of the target moving object to generate a superimposed image comprising the image superimposed with the one or more thermodynamic images,
• wherein the first feature image includes a first limb contour for the first limb part of the one or more limb parts, and the second feature image includes a second limb contour for the second limb part of the one or more limb parts.
