Foggy Cityscapes

Introduced by Christos Sakaridis et al. in Semantic Foggy Scene Understanding with Synthetic Data1 Jan 2018 archive 2025-07-28

Foggy Cityscapes is a synthetic foggy dataset which simulates fog on real scenes. Each foggy image is rendered with a clear image and depth map from Cityscapes. Thus the annotations and data split in Foggy Cityscapes are inherited from Cityscapes.

30 shown of 38 papers with a leaderboard row on this dataset's benchmarks, newest first. The archive's own "papers using this dataset" list was never published, so this is the benchmark-backed subset; the archive's count for this dataset is 249. The Syntology column is from Syntology's graph (read 2026-09-24), stated per sample; it is not part of any archive number.
