Measured effects reported in the paper
| What was changed | Where | Measured | Effect |
|---|---|---|---|
| Combine event-derived warping, synthesis, refinement, and attention averaging | Time Lens · Middlebury, Vimeo90k, GoPro, HQF, and HS-ERGB | PSNR: up to 5.21 dB improvement | Helped |
| Add attention averaging to combine synthesis and warping-based outputs (ablation) | Time Lens · Vimeo90k (denoising) validation | PSNR: 34.10 -> 35.83 | Helped |
| Add warping refinement after warping interpolation (ablation) | Time Lens · Vimeo90k (denoising) validation | PSNR: 26.68 -> 33.02 | Helped |
| Remove access to inter-frame events (ablation) | Time Lens · Middlebury, 1 frame skip | PSNR: 33.27 -> 29.03 | Hurt |
| Fine-tune on real event data (ablation) | Time Lens · HQF | PSNR: 30.57 -> 32.49 | Helped |
| Use event-derived optical flow for warping rather than relying on frame-derived flow | Time Lens · Highly dynamic interpolation | PSNR | Helped |
| Use synthesis rather than warping in regions with lighting changes or newly appearing objects | Time Lens · Highly dynamic interpolation | PSNR | Mixed |
| Use warping rather than synthesis when event data is noisy or insufficient | Time Lens · Highly dynamic interpolation | PSNR | Mixed |
