DOF-GS: Adjustable Depth-of-Field 3D Gaussian Splatting for Post-Capture Refocusing, Defocus Rendering and Blur Removal

Input Images with Defocus Blur Mip-Splatting Ours Ours (DOF Rendering) (a) (b) (c) (d) Novel View Synthesis Aperture Focal Distance Figure 1. Our method enhances 3DGS with a finite-aperture camera model and differentiable depth-of-field (DOF) rendering, enabling post-capture DOF control after training and capturing natural defocus cues from multi-view defocused images. Differentiable DOF rendering also mitigates reconstruction artifacts caused by multi-view inconsistent defocus blur. Insets (a)-(d), with in-focus areas in pink, show images rendered under various settings: (a)-(c) share aperture but differ in focal distance; (d) matches (b)'s focal distance but has a larger aperture.
