Human Activity Recognition for Edge Devices
This work addresses the challenge of deploying human activity recognition on edge devices, but it is incremental as it adapts existing methods rather than introducing a new paradigm.
The paper tackles the problem of high computational requirements for state-of-the-art video activity recognition networks like I3D and C3D, achieving comparable results with one-tenth the memory usage by modifying the testing procedure, specifically reporting 84.54% top-1 accuracy on the UCF-101 dataset using only RGB frames.
Video activity Recognition has recently gained a lot of momentum with the release of massive Kinetics (400 and 600) data. Architectures such as I3D and C3D networks have shown state-of-the-art performances for activity recognition. The one major pitfall with these state-of-the-art networks is that they require a lot of compute. In this paper we explore how we can achieve comparable results to these state-of-the-art networks for devices-on-edge. We primarily explore two architectures - I3D and Temporal Segment Network. We show that comparable results can be achieved using one tenth the memory usage by changing the testing procedure. We also report our results on Resnet architecture as our backbone apart from the original Inception architecture. Specifically, we achieve 84.54\% top-1 accuracy on UCF-101 dataset using only RGB frames.
