The Raincouver Scene Parsing Benchmark for Self-Driving in Adverse Weather and at Night
Bibliographic record
Abstract
Self-driving vehicles have the potential to transform the way we travel. Their development is at a pivotal point, as a growing number of industrial and academic research organizations are bringing these technologies into controlled but real-world settings. An essential capability of a self-driving vehicle is environment understanding: Where are the pedestrians, the other vehicles, and the drivable space? In computer and robot vision, the task of identifying semantic categories at a per pixel level is known as scene parsing or semantic segmentation. While much progress has been made in scene parsing in recent years, current datasets for training and benchmarking scene parsing algorithms focus on nominal driving conditions: fair weather and mostly daytime lighting. To complement the standard benchmarks, we introduce the Raincouver scene parsing benchmark, which to our knowledge is the first scene parsing benchmark to focus on challenging rainy driving conditions, during the day, at dusk, and at night. Our dataset comprises half an hour of driving video captured on the roads of Vancouver, Canada, and 326 frames with hand-annotated pixelwise semantic labels.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
