AMD:Anatomical Motion Diffusion with Interpretable Motion Decomposition and Fusion

no code implementations20 Dec 2023 Beibei Jing, Youjia Zhang, Zikai Song, Junqing Yu, Wei Yang

Generating realistic human motion sequences from text descriptions is a challenging task that requires capturing the rich expressiveness of both natural language and human motion. Recent advances in diffusion models have enabled significant progress in human motion synthesis. However, existing methods struggle to handle text inputs that describe complex or long motions. In this paper, we propose the Adaptable Motion Diffusion (AMD) model, which leverages a Large Language Model (LLM) to parse the input text into a sequence of concise and interpretable anatomical scripts that correspond to the target motion. This process exploits the LLM's ability to provide anatomical guidance for complex motion synthesis. We then devise a two-branch fusion scheme that balances the influence of the input text and the anatomical scripts on the inverse diffusion process, which adaptively ensures the semantic fidelity and diversity of the synthesized motion. Our method can effectively handle texts with complex or long motion descriptions, where existing methods often fail.

Optimized View and Geometry Distillation from Multi-view Diffuser

no code implementations11 Dec 2023 Youjia Zhang, Zikai Song, Junqing Yu, Yawei Luo, Wei Yang

We leverage the rendered views from the optimized radiance field as the basis and develop a two-step specialization process of a 2D diffusion model, which is adept at conducting object-specific denoising and generating high-quality multi-view images.

DiffusionTrack: Diffusion Model For Multi-Object Tracking

1 code implementation19 Aug 2023 Run Luo, Zikai Song, Lintao Ma, JinLin Wei, Wei Yang, Min Yang

In inference, the model refines a set of paired randomly generated boxes to the detection and tracking results in a flexible one-step or multi-step denoising diffusion process.
