Migician
Overview :
Migician is a multi-modal large language model developed by the Natural Language Processing Laboratory of Tsinghua University, focusing on multi-image localization tasks. By introducing an innovative training framework and the large-scale MGrounding-630k dataset, the model significantly improves the accuracy of localization in multi-image scenarios. It not only surpasses existing multi-modal large language models but also outperforms larger 70B models in performance. The main advantages of Migician lie in its ability to handle complex multi-image tasks and provide free-form localization instructions, making it have important application prospects in the field of multi-image understanding. The model is currently open-source on Hugging Face for researchers and developers to use.
Target Users :
Migician is suitable for researchers and developers in multi-modal research, computer vision, and natural language processing, especially teams that need to handle multi-image localization tasks. It provides researchers with powerful tools to explore visual and language interaction in multi-image scenarios, and provides developers with scalable solutions to build applications based on multi-image localization.
Use Cases
In multi-image scenarios, users can use natural language instructions to allow the model to locate specific objects or regions, such as finding characters that appear together in a set of images.
Researchers can use Migician's model and dataset to conduct research on multi-image localization tasks, exploring new algorithms and application scenarios.
Developers can integrate Migician into their applications to provide users with functions based on multi-image localization, such as image annotation and target tracking.
Features
Free-form multi-image localization: Supports users to perform precise target localization in multi-image scenarios through natural language instructions.
Multi-task support: Covers a variety of multi-image tasks, including common object localization, image difference localization, and free-form localization.
