LFX: Fusion-Form-Flexible Light Field Modeling for Dense Semantic Segmentation and Salient Object Detection
Overview
This research presents LFX, a flexible light field perception framework that supports both sub-aperture image and focal stack fusion settings. By introducing Field-of-Parallax Angular Subspace Modeling (FoP-ASM), the method maps feature differences to observation-specific angular markers without relying on form-specific geometric assumptions or pairwise modeling. A shared manifold subspace with regularization losses ensures semantic consistency across auxiliary observations. Evaluations on three light field datasets show LFX achieves state-of-the-art performance, reducing MAE by 12.12% and 20.59% on DUTLF-V2 and HFUT respectively under sub-aperture and focal stack settings, while achieving the best results on UrbanLF-real. Source code will be released publicly.

“n and the central image to an observation-specific angular marker. This avoids pairwise modeling among auxiliary observations and form-specific geometric assumptions. Meanwhile, a shared manifold subspace and the associated regularization losses constrain the angular residuals within a common feature space, promoting semantic consistency across auxiliary observations.
