First place in Track 3 at the AI City Challenge, ECCV 2026

About the event

ECCV, the European Conference on Computer Vision, ran from 8 to 12 September 2026 at Malmö Arena and Malmömässan. Workshops ran on 8 and 9 September. The AI City Challenge held its tenth edition there, with the workshop “Towards Sim2Real Transfer and Unified Reasoning” on the morning of 8 September.

The result

Our team took first place in Track 3, Traffic Anomaly Reasoning. The track asks a model to reason about anomalies in traffic video. The leaderboard slide shown at the workshop put Stellarview AI (India) at rank 1 in Track 3, ahead of FPT and VNPT (Vietnam), Chunghwa Telecom (Taiwan) and USTC (China).

The paper

“Reason or Recite: Complementary Specialists with an LLM Judge for Traffic Anomaly Reasoning”, by Mayur Kulkarni, was accepted as an oral paper at the workshop. Read the press release, the blog post on the method and the research page.

The same work feeds our products. VIDS detects incidents on highways, and AI Search uses vision language models to search video by description.

Our thanks go to the AI City Challenge and ECCV communities, to the organisers including Zheng Tang and Tomasz Kornuta, and to NVIDIA.
