SYNTHIA (SYNTHetic Collection of Imagery and Annotations)

Introduced by German Ros et al. in The SYNTHIA Dataset: A Large Collection of Synthetic Images for Semantic Segmentation of Urban Scenes1 Jan 2016 archive 2025-07-28

The SYNTHIA dataset is a synthetic dataset that consists of 9400 multi-viewpoint photo-realistic frames rendered from a virtual city and comes with pixel-level semantic annotations for 13 classes. Each frame has resolution of 1280 × 960.

Papers archive 2025-07-28

30 shown of 68 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 538. The Syntology column is from Syntology's graph (read 2026-09-24), stated per sample; it is not part of any archive number.
