GoMAvatar: Efficient Animatable Human Modeling from Monocular Video Using Gaussians-on-Mesh
This addresses the need for real-time, memory-efficient digital avatars in graphics and VR applications, representing a novel hybrid approach.
The paper tackles the problem of creating efficient, high-quality animatable human models from monocular video, achieving real-time rendering at 43 FPS and memory usage of 3.63 MB per subject.
We introduce GoMAvatar, a novel approach for real-time, memory-efficient, high-quality animatable human modeling. GoMAvatar takes as input a single monocular video to create a digital avatar capable of re-articulation in new poses and real-time rendering from novel viewpoints, while seamlessly integrating with rasterization-based graphics pipelines. Central to our method is the Gaussians-on-Mesh representation, a hybrid 3D model combining rendering quality and speed of Gaussian splatting with geometry modeling and compatibility of deformable meshes. We assess GoMAvatar on ZJU-MoCap data and various YouTube videos. GoMAvatar matches or surpasses current monocular human modeling algorithms in rendering quality and significantly outperforms them in computational efficiency (43 FPS) while being memory-efficient (3.63 MB per subject).
