Stage I reconstructions for evaluation (UPLight & ZJU-RGB-P)

This dataset accompanies Guided Lensless Polarization Imaging (CVPR 2026 Findings). It provides FISTA Stage-I outputs, RGB guidance images, and ground-truth polarization stacks for two public evaluation sets used in the paper.

Layout

UPLight (~1,991 scenes)

Folder	Description
UPLight/fista_grayscale/	3-channel grayscale polarization FISTA reconstructions
UPLight/fista_color/	12-channel RGB×4-angle FISTA reconstructions
UPLight/rgb_guide/	RGB guidance (equivalent unpolarized intensity)
UPLight/gt_grayscale/	Grayscale polarization GT
UPLight/gt_color/	Color polarization GT

ZJU-RGB-P (train / val splits)

Folder	Description
ZJU-RGB-P/fista_grayscale/	train_reco_grayscale/, val_grayscale_val/
ZJU-RGB-P/fista_color/	train_after_reco/, val_after_reco/
ZJU-RGB-P/rgb_guide/	train_avg_rgb/, val_avg_rgb/
ZJU-RGB-P/gt_grayscale/	train_pol_gray/, val_gt_pol_gray/
