Abstract
Human pose estimation, a key area in computer vision, benefits various fields. The comparative study of research approaches in the United States and China, both leaders in this domain, is vital for understanding and influencing global trends in this technology. This review collected 191 influential papers from 2014 to 2022, sourced from Google Scholar. The Structural Topic Model (STM) was utilized to analyze research content, preferences, and trends in research topics. Specifically, 10 topics were summarized, and topic proportions, preferences, intensities, and word clouds were displayed via visualization methods. The findings revealed: 1) research on feature extraction and depth image constituted the largest proportion, approximately 12.2%, while data training research accounted for the lowest proportion, around 7.9%; 2) the United States and China exhibited distinct research preferences: the United States focused more on model and data research, while China emphasized deep learning and neural networks; 3) both countries exhibited similar research trends within the same topics, and research on deep learning technologies has experienced a slowdown in recent years. By comparative study, this review offers valuable insights and guidance for future investigations and applications in human pose estimation, such as improving the quality and diversity of data sets.
