Ferret-v2: An Advanced Multimodal Language Model for Improved Referring, Grounding, and Visual Understanding
Konsep Inti
Ferret-v2 is a significant upgrade to the Ferret model, featuring advanced capabilities in handling any resolution referring and grounding, multi-granularity visual encoding, and a novel three-stage training pipeline, enabling it to excel in processing and understanding images with higher resolution and finer detail.
Abstrak
The paper presents Ferret-v2, an improved version of the Ferret model, which aims to enhance the capabilities of multimodal large language models (MLLMs) in detailed vision-related tasks without compromising their proficiency in global reasoning.
The key contributions are:
- Thorough analysis of higher-resolution scaling methods, finding that the "any resolution" approach outperforms "direct upsampling" in harnessing image details while retaining pre-training knowledge.
- Proposal of multi-granularity visual encoding, where the low-resolution image is encoded via CLIP, while the high-resolution sub-patches are encoded via DINOv2, to foster a deeper understanding of both global and fine-grained visual contexts.
- Introduction of a three-stage training paradigm, where an additional stage is proposed for high-resolution dense alignment before the final instruction tuning, to improve the model's spatial perception and understanding.
Extensive experiments on a wide range of tasks, including referring and grounding, visual question answering, and modern MLLM benchmarks, demonstrate the superiority of Ferret-v2 over existing works.
