Light-Field (Plenoptic) Imaging L1-080
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
A plenoptic camera samples the 4D light field L(u,v,s,t) (spatial x angular) via a main lens + microlens array (MLA) or a camera array. Each microlens projects the pupil onto an (s,t) sub-image; the 4D LF supports refocusing at any depth z via shear-integration and sub-aperture view synthesis.

Well-posedness W
- Existence:
- true
- Uniqueness:
- true
- Stability:
- conditional
- κ:
- 1500
Well-posed when MLA is calibrated and scene lies within depth-of-field cone of each sub-aperture. Degrades at occlusion boundaries, specular highlights, and beyond the angular-resolution disparity limit; MLA misregistration couples spatial and angular dimensions.
Solvability C
- Solver class:
- shear-sum refocus (analytical), epipolar-plane image (EPI) depth estimation, iterative LF super-resolution, learned (LFGAN, LFTransformer, DistgLF)
- Convergence rate q:
- 2
- Complexity:
- O(H * W * U * V) for refocus; O(U * V * H * W * log) for deep LF super-resolution
