+## HRI Dataset
+
+The High-resolution Rainy Image (HRI) dataset in the rendering stage.
+
+* `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).
