🚀 new state-of-the-art on ILIAS dataset! Curious how well the latest models can recognize particular objects? We evaluated the base and large variants of DINOv3 and Perception Encoder (PE) on instance-level image retrieval. See the results 👉 vrg.fel.cvut.cz/ilias/

Our work, GROVE, has been accepted to ICCV 2025! 🎉 This is collab. w. Cordelia Schmid & @josef-sivic.bsky.social. We will release code, models and datasets within next 2 weeks. We are also working on a search demo for the proposed datasets with user prompts! I hope to see you all in Honolulu!

We are happy to share LPOSS: Label Propagation Over Patches and Pixels for Open-vocabulary Semantic Segmentation. LPOSS is a training-free method for open-vocabulary semantic segmentation using Vision-Language Models.

You can find easy cases in older datasets, this one mostly consists of hard examples. We created a new test dataset for instance-level retrieval to better reflect real world challenges. How does your new representation or retrieval model perform on ILIAS with 100m distractors? Accepted at CVPR'25

ILIAS is a large-scale test dataset for evaluation on Instance-Level Image retrieval At Scale. It is designed to support future research in image-to-image and text-to-image retrieval for particular objects and serves as a benchmark for evaluating foundation models and retrieval techniques.
