* `clean`:  background RGB images and depth images of all scenes.
* `rainy`: rain layer images, RGB rainy images and depth rainy images of all scenes. 
* `trainset.json`: the sample lists of the training set. 
* `testset.json`: the sample lists of the test set.
* For each sample in the training set and the test set:
  * `scene`: the scene name
  * `sequence`: the viewpoint name
  * `intensity`: the rain intensity
  * `wind`:  the wind direction( all zero for the HRI dataset)
  * `background`: the path of the background RGB image
  * `depth`: the path of the background depth image
  * `rain_layer`:  the path of the rain layer image
  * `rainy_depth`: the path of the rainy depth image
  * `rainy_image`:  the path of the rainy RGB image


## BlenderFiles
 
The Blender files for rendering RGB and depth images of all viewpoints are included in the directory of each scene.

## Rain streak database

The Rain streak database from the paper [Rain Rendering for Evaluating and Improving Robustness to Bad Weather](https://github.com/astra-vision/rain-rendering).
