OMG: Open-vocabulary Motion Generation Framework


Core Concepts
OMG introduces a novel framework for compelling motion generation from zero-shot open-vocabulary text prompts.
Abstract
Recent progress in text-to-motion generation has limitations with unseen text inputs. OMG utilizes pretrain-then-finetune paradigm for realistic motion generation. MoC block aligns text embeddings to motion features effectively. Extensive experiments show significant improvements over existing methods. Contributions include scaling data and model, achieving state-of-the-art performance.

How does OMG's approach impact the democratization of motion generation

OMG's approach impacts the democratization of motion generation by enabling novices to generate compelling motions from zero-shot open-vocabulary text prompts. By carefully tailoring the pretrain-then-finetune paradigm into text-to-motion generation, OMG leverages large-scale unlabeled motion data and a novel framework to improve the alignment between text prompts and generated motions. This advancement allows individuals without extensive expertise in animation or motion capture to create realistic and diverse human character motions simply by providing textual descriptions.

What are potential challenges in implementing OMG in real-world applications

Implementing OMG in real-world applications may pose several challenges. One potential challenge is the need for significant computational resources due to the scale of training models with millions of parameters on large datasets. Additionally, ensuring that the generated motions are both realistic and aligned with the input text prompts can be a complex task requiring careful tuning of model architectures and training processes. Another challenge could be adapting OMG's framework to different types of motion styles or domains beyond human character animations, which may require additional data preprocessing and model adjustments.

How can OMG's framework be adapted for other domains beyond human character motions

OMG's framework can be adapted for other domains beyond human character motions by modifying the input data sources and adjusting the model architecture accordingly. For example, in sports analytics, OMG could be used to generate realistic player movements based on match descriptions or play-by-play commentary. In robotics, it could assist in generating dynamic movement sequences for robotic arms or autonomous vehicles based on textual commands or environmental cues. By customizing the training data and fine-tuning process, OMG's approach can be applied to various fields where generating accurate motion sequences from textual inputs is valuable.
