Measured effects reported in the paper
| What was changed | Where | Measured | Effect |
|---|---|---|---|
| Choose a frontal-slice order using a minimum-weight Hamiltonian circle before tensor recovery | TRPCA-SPV · Pavia University and Botswana hyperspectral image recovery | MPSNR | Helped |
| Choose a frontal-slice order using a minimum-weight Hamiltonian circle rather than using TRPCA's fixed order | TRPCA · Pavia University, δ=5 and c=0.05:0.1:0.25 | MPSNR: 5dB | Helped |
| Randomly permute frontal slices before recovery | Tensor nuclear norm recovery · Color video bus, tubal rank r=30 | MPSNR: 32.45dB -> 29.27dB | Hurt |
| Vary κ in TRPCA-SPV (ablation) | TRPCA-SPV · ORL and Pavia University | accuracy and PSNR | No clear effect |
