Measured effects reported in the paper
| What was changed | Where | Measured | Effect |
|---|---|---|---|
| Explicitly model the JPEG degradation with multi-layer CSC | BSD500 JPEG artifact removal · QF 5 and QF 20 | PSNR: 26.8 -> 29.05; 31.5 -> 33.5 | Helped |
| Use multi-layer CSC instead of the Zheng et al. CNN | BSD500 JPEG artifact removal · QF 10 | PSNR: 32.1 -> 31.6 | Hurt |
| Train multi-layer CSC to predict 3D trajectories | CMU motion capture trajectory reconstruction · CMU motion capture | RMSE: 35.91 -> 27.16 | Helped |
| Use a three-layer multi-layer CSC model instead of the 14-layer Trajectory CNN | CMU motion capture trajectory reconstruction · CMU motion capture | RMSE: 39.98 -> 27.16 | Helped |
| Feed the CNN the back-projected input M^T y rather than the raw measurements y | Trajectory CNN · Non-rigid trajectory reconstruction | NRMSE | Helped |
| Apply a naive CNN directly to measurements from a block-diagonal inverse problem | CNN inverse-problem reconstruction · Synthetic block recovery on BSD-500 | reconstruction performance | Hurt |
| Use CSC rather than a naive CNN as the measurement matrix shifts toward block diagonal | Synthetic inverse-problem reconstruction · BSD-500 synthetic interpolation from inpainting to block recovery | reconstruction performance | Helped |
| Train once at one quality factor and test at a mismatched quality factor | JPEG artifact removal methods · BSD500 JPEG artifact removal with quality-factor mismatch | reconstruction performance | Helped |
