Improving Gaussian Splatting with Localized Points Management

Equal contribution https://happy-hsy.github.io/projects/LPM/ 3DGS+LPM Rendered Image Gaussian Points Rendered Depth 3DGS Figure 1. Visualization of points behavior. 3DGS produces ill-conditioned Gaussians (red box) that occlude other valid points, resulting in noticeably incorrect depth estimation. LPM handles these ill-conditioned points to reduce negative impacts and further calibrate the geometry.
