SynthRSF Dataset

Overview

• SynthRSF (Synthetic with Rain, Snow, uniform and non-uniform Fog) dataset is introduced for training and evaluating adverse weather image denoising models as well as use in object detection, semantic segmentation, and depth estimation models.
• SynthRSF addresses a gap in synthetic datasets for adverse weather conditions, contributing significantly more photorealistic data compared to common 2D layered noise datasets, as well as additional modalities.
• Applications include autonomous driving, surveillance, robotics, computer-assisted search-and-rescue.

Contents

• SynthRSF:

  • 26,893 photorealistic image pairs (noisy and ground truth).
  • 14 3D scenes set in various environmental (rural/urban), contextual (indoor/outdoor) and lighting conditions (day/night).
  • Created using Unreal 5.2 engine.

• SynthRSF-MM expansion:

  • 13,800 additional pairs are accompanied by:
  • 16-bit depth maps.
  • Pixel-accurate object annotations for 41 object classes.

SynthRSF-MM Dataset

Overview

SynthRSF-MM is an expansion of the SynthRSF dataset, including additional modalities for a comprehensive analysis in computer vision tasks. It contains 13,800 noisy images from 14 scenes with ground truth on additional modalities.

SynthRSF-MM Example

Ground truth	Depth map	Object annotations
Fog	Rain	Snow

A sample scene from SynthRSF-MM, showing the ground truth (clear) scene, depth map, semantic segmentation stencil mask, and three noisy variants with different weather conditions. For each Ground truth image, there is one depth map, five pixel-level annotations and 8 noisy images per phenomenon.
