The Cityscapes dataset is a large-scale collection of street scene sequences from 50 cities, containing high quality pixel-level annotations for 5,000 frames and additional weakly annotated frames. It is designed to support research in semantic urban scene understanding tasks such as pixel-level, instance-level, and panoptic semantic labeling. The dataset can be downloaded and loaded into the FiftyOne toolset, which helps data science teams improve computer vision models by curating high quality datasets, evaluating models, visualizing embeddings, and getting to production faster.
