# Optical Flow Visualization

Python port of the optical flow visualization: [people.csail.mit.edu/celiu/OpticalFlow/](https://people.csail.mit.edu/celiu/OpticalFlow/).

This implementation is based on the color wheel presented in:

```

S. Baker, D. Scharstein, J. Lewis, S. Roth, M. J. Black, and R. Szeliski.

A database and evaluation methodology for optical flow.

In Proc. IEEE International Conference on Computer Vision (ICCV), 2007.

```

## Installation

    pip install flow_vis

## Usage

    import flow_vis

    flow_color = flow_vis.flow_to_color(flow_uv, convert_to_bgr=False)

## Examples visualizations

Example visualization from the MPI Sintel Dataset:
