Motion generation is a dynamic and challenging domain within computer vision dedicated to creating realistic human actions in digital environments. Its applications span animation, virtual reality, and interactive media, enabling the production of lifelike, human-centric animations. However, generating complex human motions, particularly those aligned with detailed spatiotemporal descriptions, has remained a significant hurdle. Existing methods, though advancing the field, often need to catch up in capturing the nuanced, fine-grained aspects of human movements.
The presented research introduces FineMoGen, a novel framework by S-Lab, Nanyang Technological University, and Sense Time Research to address these limitations. Building upon the foundations of diffusion models, FineMoGen leverages a unique transformer architecture named Spatio-Temporal Mixture Attention (SAMI). This approach significantly enhances the model’s ability to synthesize human motions that are both spatially and temporally detailed, adhering closely to user inputs. The SAMI mechanism within FineMoGen is instrumental in realizing this goal. It enables the model to interpret and implement fine-grained textual instructions, translating them into accurate and lifelike motion sequences.
Central to FineMoGen’s methodology is its advanced handling of spatial and temporal dynamics. The framework is adept at breaking down complex motion instructions into distinct spatial components, corresponding to various body parts and temporal segments, defining the sequence of movements over time. This granular approach allows for a more accurate representation of human actions, ensuring that each movement is consistent with the instructions in space and time. Moreover, FineMoGen incorporates sparsely activated Mixture-of-Experts (MoE) within its architecture, further enhancing its ability to capture and reproduce intricate motion details.
The performance of FineMoGen is a testament to its innovative design. The model has been rigorously tested against various benchmarks in motion generation, where it consistently outperforms existing state-of-the-art methods. Its ability to generate natural, detailed human motions based on fine-grained textual descriptions is unparalleled. Furthermore, FineMoGen introduces zero-shot motion editing capabilities, allowing users to modify generated motions with new instructions, a feature not commonly found in previous models. This editing feature and the model’s inherent generation capabilities represent a significant leap forward in digital motion synthesis.
The research’s contribution extends beyond the development of a new model. It includes the establishment of a large-scale dataset with fine-grained spatiotemporal text annotations, further enriching the resources available for future research in this area. This dataset and FineMoGen’s demonstrated capabilities pave the way for more realistic and detailed human motion generation in various applications, from entertainment to virtual training.
FineMoGen’s introduction marks a pivotal advancement in motion generation. Its ability to generate and edit human motions with a high degree of detail and accuracy positions it as a groundbreaking tool in the field. The model’s nuanced understanding of human movements, driven by detailed textual inputs, sets a new standard for what can be achieved in digital motion generation and editing.
