Physgen
Overview :
PhysGen is an innovative method for image-to-video generation that transforms a single image and input conditions (such as force and torque applied to objects in the image) into realistic, physically plausible, and temporally coherent videos. This technology achieves dynamic simulation in image space by combining model-based physical simulation with data-driven video generation processes. The main advantages of PhysGen include producing videos that are both physically and visually realistic, and offering precise control, demonstrating its superiority over existing data-driven image-to-video generation methods through quantitative comparisons and comprehensive user studies.
Target Users :
The target audience includes animators, video editors, game developers, and any professionals who need to convert static images into dynamic video content. The realistic physical simulation and precise control provided by PhysGen make it an ideal choice for these professionals, as it enhances their workflow and produces high-quality visual content.
Use Cases
Animators use PhysGen to convert concept art into animated trailers.
Game developers leverage PhysGen to generate realistic physical interaction animations for game characters.
Video editors utilize PhysGen to add dynamic effects to static scenes, enhancing visual impact.

Animate Anyone
Animate Anyone aims to generate character videos from static images driven by signals. Leveraging the power of diffusion models, we propose a novel framework tailored for character animation. To maintain consistency of complex appearance features present in the reference image, we design ReferenceNet to merge detailed features via spatial attention. To ensure controllability and continuity, we introduce an efficient pose guidance module to direct character movements and adopt an effective temporal modeling approach to ensure smooth cross-frame transitions between video frames. By extending the training data, our method can animate any character, achieving superior results in character animation compared to other image-to-video approaches. Moreover, we evaluate our method on benchmarks for fashion video and human dance synthesis, achieving state-of-the-art results.
