Scalability of continuous-time score-based equivariant imaging for hyperspectral inpainting

Investigate the scalability of the concurrent continuous-time score-based formulation introduced by Levac et al. when applied to hyperspectral image inpainting.

Background

The paper contrasts its discrete-time HyDiff-EI framework with a concurrent continuous-time score-based formulation that incorporates equivariant imaging. Although the cited formulation is identified as a related development, its practical scalability for hyperspectral image inpainting has not been established. The unresolved issue concerns whether the continuous-time approach can handle the dimensionality and computational demands of hyperspectral inpainting effectively.

References

A concurrent work (not yet published) introduces a continuous-time score-based formulation; however, its scalability when applied to hyperspectral inpainting remains to be investigated.
