Minimal Angular Sampling for Arbitrary-View Light Field Reconstruction Using Spectral-Angular View Selection

Dense light field acquisition provides many angular observations of the same scene, but using all available views can introduce redundancy, disparity-related inconsistency, and unnecessary computational cost. This paper addresses the problem of minimal angular sampling for arbitrary-view light field reconstruction. Ins...

Frequency-Guided Multi-View Super-Resolution for Light Field Images

Light field imaging captures both spatial and angular information but suffers from an inherent trade-off that limits per-view spatial resolution. This work addresses center-view super-resolution (SR) from multi-view inputs and reveals that naive view aggregation fails to effectively exploit angular information, even as...

Lightweight Cross-View Gradient Variance for Adaptive Density Control in 3D Gaussian Splatting

3D Gaussian Splatting has become an effective representation for real-time novel view synthesis by optimizing explicit 3D Gaussian primitives from a set of posed images. A key component of this framework is adaptive density control, where Gaussians are cloned, split, or pruned during training to improve scene coverage...
