Action100M: A Deep Dive into a Million-Scale Video Action Understanding Dataset

In the field of artificial intelligence, particularly computer vision and video understanding, high-quality, large-scale datasets are the critical foundation for driving technological progress. Today, we take an in-depth look at a significant resource released by Meta FAIR in collaboration with several top academic institutions—Action100M. This is a project aimed at advancing fine-grained video action understanding through a massive dataset. This article will provide a comprehensive and thorough explanation, from the dataset’s composition and core features to its specific usage. Dataset Overview: Scale and Source Action100M, as the name suggests, targets a scale of one million annotated video segments. Currently, the …
