Latent-to-4D 方法可从视频潜在表示生成可复用的三维场景

研究人员开发了 Latent-to-4D,一种从文本或图像生成动态三维场景的新颖方法。该方法通过将视频扩散潜在表示与四维解码器直接对齐,绕过了重建 RGB 视频的需要。在相同的变分自编码器家族内,单个训练好的检查点可以跨不同的视频扩散 Transformer 重用,在 Text4D-200 和 I4D-200 等基准测试中展示了比现有方法更好的性能和人类偏好。 AI

影响 能够更高效、可复用地生成动态三维场景,可能对虚拟现实和内容创作等领域产生影响。

    超越像素:从视频先验到四维世界

    4D generation synthesizes dynamic 3D scenes from conditions such as text or images. Existing methods either reconstruct generated RGB videos with a separate 4D model or adapt a particular video generator to predict geometry directly. The former suffers from distribution mismatch …
