There is a lot of work done recently on composed image retrieval, but we felt that none of the existing benchmarks reflect the real-world challenges and applications. So, we created a new test benchmark for instance-level composed image retrieval.
🎉 Instance-level Composed Image Retrieval @ #NeurIPS2025
🎨 Task: given (image of an object instance) + (text modification), retrieve photos of that exact instance under the change.
E.g.: Temple of Poseidon 🏛️ ➕ during sunset 🌅

The hidden flaws in your favorite foundation model: We've uncovered how subtle image metadata (JPEG params, camera type, etc.) systematically biases visual representations and consequently affect the object recognition ability. To be presented at #ICCV2025 as a highlight paper.
Have you ever asked yourself how much your favorite vision model knows about image capture parameters (e.g., the amount of JPEG compression, the camera model, etc.)? Furthermore, could these parameters influence its semantic recognition abilities?
