## Overview

This project contains human perceived optical flow/motion data derived from images obtained from several third-party benchmark datasets. The images and labels used in this project originate from these publicly available datasets. **Before using any images or labels, please consult and comply with the respective licenses and usage agreements provided on their official websites.**

This project is intended for research and non-commercial use only. If you plan to use any of the data for commercial purposes, you must first obtain proper authorization from the respective dataset providers.

## Third-Party Datasets and Reference Websites

The project makes use of the following 10 benchmark datasets:
