Algorithm evaluation reveals post-capture refocusing and defocus rendering across blurry multi-view images, indicating superior depth-of-field control in novel view synthesis.

Key Points

To introduce a 3D Gaussian Splatting framework utilizing a finite-aperture camera model that enables post-capture depth-of-field adjustment and blur removal from multi-view images.
Formulated a 3D Gaussian Splatting pipeline with a finite-aperture camera model and explicit, differentiable defocus rendering.
Trained the system on multi-view images exhibiting uncalibrated, moderate defocus blur.
Extracted circle-of-confusion cues during optimization to isolate in-focus scene regions and guide sharp 3D reconstruction.
Reconstructed sharp, all-in-focus 3D scene details from multi-view image sets affected by uncalibrated defocus blur.
Achieved flexible post-capture camera refocusing alongside continuous, on-demand adjustment of synthetic aperture and focal distance.
