## Highlights
- **Optical flow** or **optic flow** is the pattern of apparent [motion](https://en.wikipedia.org/wiki/Motion_(physics)) of objects, surfaces, and edges in a visual scene caused by the [relative motion](https://en.wikipedia.org/wiki/Relative_motion) between an observer and a scene.[[1]](https://en.wikipedia.org/wiki/Optical_flow#cite_note-1)[[2]](https://en.wikipedia.org/wiki/Optical_flow#cite_note-2) Optical flow can also be defined as the distribution of apparent velocities of movement of brightness pattern in an image.[[3]](https://en.wikipedia.org/wiki/Optical_flow#cite_note-3) ([View Highlight](https://read.readwise.io/read/01hygvnasnnnqqk5t156fy63dy))
