Coded Aperture Compressive Temporal Imaging (CACTI) L1-027
Unclaimed Principle — open for contribution
This Principle is declared in the catalog but has no reference solver, no pinned dataset, and is not registered on-chain. There is no reward pool. Submitting a cert against this Principle today will record the cert for reproducibility but pay zero PWM.
To claim it as a Bounty #7 contribution: open a PR adding (1) a reference solver, (2) ≥1 dataset pinned to IPFS, (3) updates to the L3 manifest with dataset CIDs. After verifier-agent triple-review, the founders' 3-of-5 multisig signs PWMRegistry.register() and the Principle becomes mineable.
Forward model E
Single-shot compressive video forward model: a temporally varying binary coded mask gates photons per-pixel for each sub-frame, and the detector integrates all B masked sub-frames into a single 2D snapshot.
L-DAG
Well-posedness W
- Existence:
- true
- Uniqueness:
- true
- Stability:
- conditional
- κ:
- 2500
B:1 underdetermined compressive video recovery; temporally varying binary masks satisfy RIP-like conditions; sub-pixel mask mismatch is dominant stability risk (EfficientSCI drops 20.58 dB under severe mismatch).
Solvability C
- Solver class:
- iterative_proximal (GAP-TV, DeSCI) or plug-and-play (PnP-FFDNet) or learned unrolling (EfficientSCI, BIRNAT)
- Convergence rate q:
- 2
- Complexity:
- O(H * W * B * log(H*W*B)) per iteration
