: This drastically reduces the processing power needed compared to evaluating every single frame.

: Detect simple structures like edges, corners, or textures.

If you are looking for information on a specific video file or a particular coding implementation, Learn how to to your own video datasets?

: The network runs expensive computations only on occasional "key frames".

: Features are extracted without manual programming, capturing the most relevant information for a specific task. Hierarchical Structure :

: It uses a lightweight "flow field" to pass those feature maps to subsequent frames.
