Floaters from overfit #6

Firstly, I want to express my sincere gratitude for open-sourcing such an outstanding project. While validating on my own dataset, I observed significant improvements in PSNR and SSIM, but inevitably encountered the issue of floaters. This problem became more pronounced, especially when the densify_grad_threshold was reduced from 0.0004 to 0.0002. Have you encountered similar issues? If so, how did you address them? image The image above is an example of NVS. I slightly shifted the view to the right （about 1m）, and noticeable floaters are still present even when rendering from the original viewpoint.

This might be due to the input image being relatively sparse. Could you show me the camera trajectory? If it's convenient, you can add me on WeChat. My email is 424117920@qq.com.
