This invention relates to the fields of wireless sensing and deep learning, specifically to a human pose estimation method based on a multimodal attention network. In video modality learning, a multi-resolution network (FCN) is designed to extract pose features. By applying a local self-attention network to the generated heatmap, the weights and attention levels of different regions are adaptively adjusted to capture more refined keypoint information.
