1. A method for detecting a body, the method comprising:
acquiring a set of candidate body image regions in a target image, based on a body detection model;
for a candidate body image region in the set of candidate body image regions: acquiring position information and confidences of candidate body key points in the candidate body image region, based on a single body key point detection model; determining the candidate body key points within a body contour based on body contour information in the candidate body image region and the acquired position information of the candidate body key points; and determining a confidence score of the candidate body image region based on a sum of the confidences of the candidate body key points within the body contour; and
determining a body image region from the set of candidate body image regions, based on confidence scores of the candidate body image regions in the set of candidate body image regions.
