A lighter network (like FlowNet) that estimates the motion between frames.
A heavy network (like ResNet) extracts "deep features" only from select frames. 5faafede261a08fdaba46_source.mp4
This allows for high-speed recognition because computing optical flow is much faster than running a full deep neural network on every single frame. 🛠️ Key Components A lighter network (like FlowNet) that estimates the
