Practical Solutions and Value of Evaluating Geometric Awareness in Large-Scale Vision Models for Long-Term Point Tracking
Overview
The strong generalization abilities of large-scale vision foundation models have led to remarkable performance in various computer vision tasks. These models are highly adaptable and can handle tasks like object recognition, picture matching, and 3D reconstruction without extensive task-specific training.
Challenges in Long-Term Correspondence Tasks
However, there is a significant challenge in long-term correspondence tasks in dynamic and complicated situations, such as tracking the same physical point over time in video sequences. This complexity is crucial for applications like autonomous driving, robotics, and object tracking in surveillance.
Research Approach
To address this challenge, researchers have evaluated the geometric awareness of visual foundation models in point tracking. They conducted experiments in three different setups to assess the models’ tracking ability and geometric properties.
Experimental Setups
- Zero-Shot Setting: Evaluating the model’s tracking ability without further training.
- Using Low-Capacity Layers for Probing: Adding low-capacity layers to probe geometric information within the model.
- Fine-Tuning with Low-Rank Adaptation (LoRA): Using Low-Rank Adaptation to fine-tune the foundation model.
Key Findings
The research revealed that models like Stable Diffusion and DINOv2 demonstrated strong geometric correspondence abilities even without extra training. DINOv2 showed promising performance in the adaptation scenario, indicating its potential for tasks involving long-term correspondence.
Implications
This research expands the application range of large-scale vision models, making them suitable for sophisticated computer vision tasks like object tracking and autonomous systems. The models were evaluated in various scenarios, showcasing their potential for practical use.
