Researchers have developed a novel point-supervised framework for skeleton-based human action segmentation, significantly reducing the need for extensive frame-level annotations. This method utilizes multimodal skeleton data, including joint, bone, and motion information, to extract rich features. By integrating multimodal pseudo-labeling techniques with existing clustering and energy function methods, the framework generates reliable pseudo-labels to guide model training. Experiments on benchmarks like PKU-MMD, MCFS-22, and MCFS-130 demonstrate that this approach achieves competitive performance, even outperforming some fully-supervised methods while drastically cutting down annotation costs.
