Measured effects reported in the paper
| What was changed | Where | Measured | Effect |
|---|---|---|---|
| use the jointly optimized rank-1 DOE and tailored reconstruction network | single-shot HDR imaging · Test set | PSNR: 48.26 vs. 40.30 | Helped |
| replace the proposed reconstruction network with Deep Optics (ablation) | learned PSF HDR reconstruction · Test set | PSNR: 48.26 -> 37.91 | Hurt |
| replace the proposed reconstruction network with HDR-CNN (ablation) | learned PSF HDR reconstruction · Test set | PSNR: 48.26 -> 33.51 | Hurt |
| replace the learned PSF with Dual Peak PSF (ablation) | proposed reconstruction network · Test set | PSNR: 48.26 -> 43.08 | Hurt |
| replace the learned PSF with Star PSF (ablation) | proposed reconstruction network · Test set | PSNR: 48.26 -> 42.62 | Hurt |
