Video Action Recognition

Abstract

Our brain is a superfast action recognition system that's hard to match. In terms of deep learning, our brain routinely does many things to recognize actions, and it works fast! In this chapter we cover practical methods and tools for video action recognition and classification. We discuss data structures for loading, normalizing, and storing videos; datasets for sport action classification, such as Kinetics; and deep learning models. Using readily available pretrained models, we can classify hundreds of sport actions and train the models to recognize new activities. For a sport data scientist, this chapter provides practical examples for deep learning, movement analysis, and action recognition for video.
