FreeTimeGS: Free Gaussian Primitives at Anytime Anywhere for Dynamic Scene Reconstruction

25.98 dB 26.75 dB Figure 1 . Photorealistic and real-time rendering of dynamic 3D scenes. Our method achieves the best performance on challenging dynamic scenes with fast and complex motion. Compared with current state-of-the-art methods 4DGS [48] and STGS [21], our PSNR is improved by 2.4dB and 1.4dB on the SelfCap dataset. For dynamic regions, our PSNR is improved by 4.1dB and 2.6dB. What's more, our method supports real-time rendering at 1080p resolution with a speed of 450 FPS using a single RTX 4090 GPU.
