LFSRDiff: Light Field Image Super-Resolution via Diffusion Models

1 code implementation • 27 Nov 2023 • Wentao Chao, Fuqing Duan, Xuechun Wang, Yingqian Wang, Guanghui Wang

Despite this complexity, mainstream LF image SR methods typically adopt a deterministic approach, generating only a single output supervised by pixel-wise loss functions.

OccCasNet: Occlusion-aware Cascade Cost Volume for Light Field Depth Estimation

1 code implementation • 28 May 2023 • Wentao Chao, Fuqing Duan, Xuechun Wang, Yingqian Wang, Guanghui Wang

To address this issue and achieve a better trade-off between accuracy and efficiency, we propose an occlusion-aware cascade cost volume for LF depth (disparity) estimation.

Learning Sub-Pixel Disparity Distribution for Light Field Depth Estimation

2 code implementations • 20 Aug 2022 • Wentao Chao, Xuechun Wang, Yingqian Wang, Guanghui Wang, Fuqing Duan

However, the disparity map is only a sub-space projection (i. e., an expectation) of the disparity distribution, which is essential for models to learn.
