Optimizing the Interactive Video Retrieval Tool Vibro for the Video Browser Showdown 2024

Vibro (Video Browser) is an interactive video retrieval system and the winner of the Video Browser Showdown 2022 and 2023. This paper gives an overview of the underlying concepts of this tool and highlights the changes that were implemented for the upcoming competition of 2024. Additionally, we propose a way to evaluate retrieval engine performance for the specific use case of known-item search, by using logged query data from previous competitions. This evaluation helps in finding an optimal embedding model candidate for image- and text-to-image retrieval and making the right decisions to improve the current system.
