Abstract： It is difficult to predict the correct human poses when facing the challenge of the scale change of the feature map in the human pose estimation. To solve this problem, proposing a high-resolution network MSANet (Multiscale-Attention Net) based on multi-scale attention mechanism to improve the detection accuracy of human pose estimation. Introduce lightweight pyramid convolution and attention feature fusion to achieve more efficient extraction of multi-scale information; citing the self-transformer module in the fusion of parallel subnets for feature enhancement to obtain global features; in the output stage, The features of each layer are fused using an adaptive spatial feature fusion strategy as the final output, which more fully obtains the semantic information of high-level features and the fine-grained features of low-level features to infer invisible points and occluded key points. Tested on the public dataset COCO2017, the experimental results show that this method improves the estimation accuracy by 4.2% compared with the basic network HRNet.
