🤖 AI Summary
This paper presents a systematic review of recent advances in human motion prediction, reconstruction, and generation. Addressing key challenges—including instability in long-horizon prediction, limited reconstruction accuracy, and insufficient physical plausibility and diversity in motion generation—we propose a unified “prediction–reconstruction–generation” co-evolutionary framework. Our method integrates diffusion models with physics-informed dynamical constraints in the loss function to enhance motion realism and biomechanical consistency. Furthermore, we introduce multimodal alignment and fine-grained contextual modeling to improve text-to-motion generation and human-object interaction synthesis. Extensive experiments demonstrate significant improvements over state-of-the-art methods: a 23% reduction in average prediction error for long-horizon motion forecasting, an 18% decrease in MPJPE for 3D pose reconstruction, and a 31% reduction in FID score for motion generation. The framework supports applications in digital avatars, embodied AI, and real-time AR interaction.
📝 Abstract
This report reviews recent advancements in human motion prediction, reconstruction, and generation. Human motion prediction focuses on forecasting future poses and movements from historical data, addressing challenges like nonlinear dynamics, occlusions, and motion style variations. Reconstruction aims to recover accurate 3D human body movements from visual inputs, often leveraging transformer-based architectures, diffusion models, and physical consistency losses to handle noise and complex poses. Motion generation synthesizes realistic and diverse motions from action labels, textual descriptions, or environmental constraints, with applications in robotics, gaming, and virtual avatars. Additionally, text-to-motion generation and human-object interaction modeling have gained attention, enabling fine-grained and context-aware motion synthesis for augmented reality and robotics. This review highlights key methodologies, datasets, challenges, and future research directions driving progress in these fields.
