FEATURE EXTRACTION OF GYMNASTICS IMAGES BASED ON MULTI-SCALE FEATURE FUSION ALGORITHM

The feature extraction and analysis of gymnastics images is an essential foundation for estimating human posture. The primary step is to obtain various joint points of athletes based on basic information such as human texture and contour in the sports images. The reconstruction and analysis of the human skeleton is completed based on the feature data of the joint points. In this process, traditional algorithm models often have certain shortcomings in the accuracy of feature extraction for motion images. This paper combines multi-scale feature fusion algorithms to construct a gymnastics motion image feature extraction model, which can achieve more accurate and efficient analysis and research for the feature extraction process of motion images, further improving the detection accuracy of joint points in motion images; this lays an essential foundation for feature extraction of gymnastics images. At the same time, it also provides more methods for skeleton reconstruction based on image feature information during the motion process, improving the efficiency and accuracy of reconstruction.
