Researchers from the University of Hong Kong, Alibaba Group, and Ant Group developed LivePhoto to solve the problem of temporal motions that are overlooked in current text-to-video generation studies. LivePhoto allows users to animate images with text descriptions while reducing ambiguity in text-to-motion mapping.
The studio addresses the limitations of existing image animation methods by introducing LivePhoto, a practical system that allows users to animate images with text descriptions. Unlike previous work that relies on specific videos or categories, LivePhoto uses text as a flexible control to generate personalized videos in universal domains. The field of text-to-video generation has evolved, with recent approaches leveraging pre-trained text-to-image models and introducing temporal layers. LivePhoto overcomes the challenges by allowing users to control the intensity of motion through text, providing a versatile and customizable framework for text-based image animation across multiple domains.
LivePhoto is a system that allows users to animate images with text descriptions. With LivePhoto, users have precise control over the intensity of motion, making it easy to decode motion-related textual instructions in videos. This highly flexible and customizable system allows users to generate diverse content from textual instructions. LivePhoto is a valuable contribution to text-based image animation.
The system incorporates a motion module, a motion intensity estimation module, and a text reweighting module for effective text-to-motion mapping, addressing challenges in text-to-video generation. Using the Stable Diffusion model introduces additional modules and layers for motion control and text-guided video generation. LivePhoto uses content encoding, cross-attention, and noise inversion as a guide, making it easy to create personalized videos based on textual instructions while preserving overall identity.
LivePhoto excels at decoding motion-related textual instructions in videos, showing its ability to control temporal motions with text descriptions. LivePhoto gives users an additional control cue to customize motion intensity, offering flexibility to animate images with text descriptions. The system uses Stable Diffusion as a base model, enhanced with modules and layers to enable effective text-to-video generation and motion control.
In conclusion, LivePhoto is a practical and flexible system that allows users to create animated images with customizable motion control and text descriptions. Its motion module for temporal modeling and intensity estimation decodes textual instructions in various videos, making it effective in different actions, camera movements and content. Its wide applications make it a useful tool for creating animated images based on text instructions.
To improve LivePhoto, exploring higher resolutions and robust models like SD-XL can significantly improve overall performance. Addressing the issue of motion speed and magnitude description in text can improve motion-consistent alignment. Using super-resolution networks as post-processing can improve video smoothness and resolution. Improving the quality of the training data could improve the image consistency in the generated videos. Future work could refine the training process and optimize the movement intensity estimation module. Investigating the potential of LivePhoto in various applications and domains is a promising avenue for future research.
