TrackGo: A New AI Tool for Precise and Controllable Video Generation
Beijing, China – Researchers at the Institute of Automation, Chinese Academy of Sciences, have developed a groundbreaking AI video generation technology called TrackGo. This new technology allows users to control the movement of objects within a video with unprecedented precision, openingup exciting possibilities for various industries.
TrackGo utilizes a novel approach that combines user-defined masks and arrows with a specially designed adapter called TrackAdapter. Thisadapter seamlessly integrates with pre-trained video generation models, enabling them to understand and respond to user-specified movement instructions.
How TrackGo Works:
- User Input: Users begin by outlining the target object or region withina video using a free-form mask. They then draw arrows to indicate the desired movement trajectory of the object.
- Point Trajectory Generation: TrackGo automatically extracts point trajectories from the user-defined masks and arrows. These trajectoriesserve as a precise blueprint for the video generation process.
- Attention Map Manipulation: TrackAdapter leverages the time-based self-attention layers within the video generation model to identify and activate regions corresponding to the specified movement. This allows for precise control over specific parts of the video frames.
- Dual-Branch Architecture: TrackAdapter introduces an additional self-attention branch that operates in parallel with the original branch. This dedicated branch focuses on the target region’s movement, while the original branch continues to process other areas.
- Video Generation: Based on the input point trajectories and the guidance provided by TrackAdapter, the model generates a series of video frames, creating a coherent video that conforms to the user-defined movement.
Key Features of TrackGo:
- Precise Control: TrackGo allows users to control the movement of objects within videos with high accuracy, thanks to the combination of user-defined masks,arrows, and the TrackAdapter.
- Efficient Performance: TrackGo maintains computational efficiency while achieving fine-grained control over video generation, minimizing additional computational overhead.
- Advanced Evaluation Metrics: The technology is evaluated using key metrics like FVD, FID, and ObjMC to ensure high standards in video quality,image quality, and motion fidelity.
Applications of TrackGo:
- Film and Television: TrackGo can be used to generate or modify specific scenes in post-production, such as adding or adjusting object movement without the need for reshooting.
- Animation: Animators can leverage TrackGo to controlthe precise movements of animated characters or objects, enhancing animation production efficiency and quality.
- Virtual Reality (VR) and Augmented Reality (AR): TrackGo can generate dynamic video content that synchronizes with user interaction in VR or AR applications, enhancing the immersive experience.
- Game Development: Game designers canutilize TrackGo to create complex game animations and special effects, bringing game characters and environments to life.
