Online Action Detection

Online action detection (OAD) focuses on real-time identification of actions within streaming video, a crucial task for applications like video surveillance and human-computer interaction. Recent research emphasizes developing efficient and accurate models, often employing transformer-based architectures with multi-scale feature extraction and mechanisms for handling long-term temporal dependencies and overlapping actions. These advancements aim to improve both the speed and accuracy of action detection, addressing challenges such as limited computational resources and the need for robust handling of complex real-world scenarios. The resulting improvements have significant implications for various fields requiring real-time video understanding.
