Frequency Domain Analysis-based metrics

[jmichel-otb]

I recently wrote the following paper with is undergoing review : https://hal.science/hal-04723225v1

It heavily relies on PIQ for implementation.

In this paper, I derive a new set of Frequency Domain Analysis Image Quality metric, which allow to precisely analyse the performance of super-resolution algorithms in terms of spatial frequency restoration (see section II.C).

I was wondering if PIQ would consider a code contribution to include those new metrics in the library.

It would make more sense to me than distributing them with the paper code.

Any thoughts ?
