About

What is GPS-Gaussian?

GPS-Gaussian is an innovative AI tool that offers a generalizable pixel-wise 3D Gaussian representation for real-time human novel view synthesis. Developed as a highlight of CVPR 2024, this tool allows for instant generation of novel views of unseen characters without requiring any fine-tuning or optimization. It provides a robust solution for computer vision and graphics researchers and developers working with 3D human models. The repository includes detailed instructions for installation, dataset preparation, and training, supporting both synthetic and real-world data. Users can pretrain a depth prediction model and then train the full model, with options for offline disparity determination to speed up subsequent training. Pretrained models are also available for quick evaluation and testing.

Best used for

Ideal for developers and data scientists who need to generate novel views of human subjects, process 3D human data, and conduct research in computer vision. Especially valuable for applications requiring real-time performance and generalizability without extensive fine-tuning.

FAQs

What kind of data is required to train GPS-Gaussian?

GPS-Gaussian can be trained using both synthetic and real-world human datasets. The project provides a rendered THuman2.0 dataset for training in a 16-camera setting, and recommends collecting more human scans from sources like Twindom or Render People for a more robust model.

Does GPS-Gaussian require extensive computational resources for training?

Training involves two stages: pretraining a depth prediction model and then training the full model. An initial offline stereo rectification and disparity determination process can take several hours but significantly speeds up subsequent training schemes. Users can opt to skip this preprocessing if needed.

Can GPS-Gaussian be used for real-time applications?

Yes, GPS-Gaussian is designed for real-time human novel view synthesis. Its generalizable pixel-wise 3D Gaussian representation allows for instant generation of novel views without the need for fine-tuning or optimization, making it suitable for real-time scenarios.
