The **High-resolution Rainy Image (HRI) dataset** is a synthetic dataset created through a learning-from-rendering approach, detailed in the paper [Learning from Rendering: Realistic and Controllable Extreme Rainy Image Synthesis for Autonomous Driving Simulation](https://huggingface.co/papers/2502.16421). Designed for autonomous driving simulation, HRI provides realistic and controllable extreme rainy images to enhance visual perception models. It comprises 3,200 paired rainy-clean images, along with corresponding depth and rain layer mask images, captured across three diverse scenes (lane, citystreet, and japanesestreet) at a high resolution of 2048x1024. This dataset is particularly valuable for tasks such as semantic segmentation, instance segmentation, depth estimation, and object detection in challenging weather conditions, as demonstrated in the related work with the CARLARain simulator.
