IDMR-8B

IDMR is a universal multimodal embedding model, particularly well-suited for Instance-Driven Multimodal Retrieval (IDMR) tasks. It is designed to achieve fine-grained, instance-level visual correspondence across modalities.

🚀 Usage

To get started, clone the GitHub repository and install the required dependencies:

bash

git clone https://github.com/BwLiu01/IDMR.git
cd IDMR
pip install -r requirements.txt

python
