This dataset contains the generated weather configurations as png and npz files.

Python, 3.10.12

This dataset contains the weather data files to replicate the results from our publication, and to test the robustness of further optical flow methods under diverse weather effects.

We provide the randomly weather-augmented versions of the Sintel dataset as .png files (the respective files are called _png.zip) for all weather configurations from the paper. Note that the four main weather variants (snow, rain, sparks and fog) correspond to the following configurations: snow=particles_3000, rain=rain_1500, sparks=color_additive_red, fog=size_fog. A smaller dataset sample that contains selected scene samples for the four main augmentations can be found in weather_sampledata.zip . In addition to the .png files we also provide the raw weather data as loadable .npz files (the respective datasets are called _npz.zip), which can be processed with the provided code.

Overall, we provide the following files:
