Multimodal AI

Our work focuses on advancing multimodal AI by integrating large language models with vision systems for tasks such as contextual object detection, embodied AI, and multimodal reasoning. We explore how large-scale models can enhance perception, understanding, and decision-making across diverse real-world scenarios.

Editing and Generation

Our work in image and video editing focuses on advancing AI-driven manipulation and generation techniques for more realistic, efficient, and controllable content creation. From stable video matting and dialog-based fine-grained facial editing to high-resolution style transfer and diffusion-based video synthesis, we develop cutting-edge models that push the boundaries of visual editing and interactive media.
