This project is developed by Alibaba Intelligent Computing Research Institute. You only need to provide a static character image and some preset action (or pose sequences), and then generate an animated video of the character.
Simultaneously maintain consistency in the appearance and features of the characters in the image.
In theory, “animating anyone” This method is not only applicable to human characters, but can also be used for anime/cartoon characters, humanoid characters, etc., and has a wide range of applications.
Working principle: In this process, the first step is to obtain an image of a character, which can be a human, anime character, or any character image with clear features. Then, the user provides a series of actions or postures, which can be any type of action, such as dancing, walking, or other movements.
Technically, this process involves several key steps:
- Pose guidance: The AI system first analyzes the provided action sequence. These action sequences are used to guide the characters in the image on how to move.
- Feature fusion: The system uses advanced algorithms such as ReferenceNet to ensure that the detailed features of characters (such as facial expressions, clothing details, etc.) remain consistent during the animation process.
- Video synthesis: Through techniques such as denoising and UNet, the system synthesizes actions and static images into a coherent video sequence, ensuring smooth and natural character movements.
- Attention mechanism: During the synthesis process, the system utilizes mechanisms such as spatial attention, cross attention, and temporal attention to ensure that each frame in the video maintains a high degree of consistency with the original image. The innovation of this technology lies in its versatility and high degree of customization ability. Users can create unique and customized video content using any image and any action sequence. This is a very valuable tool for anyone who needs to create animation content quickly and efficiently. Through this technology, fascinating animated videos can be created without the need for complex animation skills or expensive software.
