Inspired by scikit's implementation.

Any chance we could get this merged/reviewed?

Hi @Mattwmaster58,

Any reason for not using Scikit-Image conversion? It is already there, vectorised and unit tested.

Mattwmaster58 commented 2 years ago

Sometimes one may prefer a "lighter" library.

KelSolaar commented 2 years ago

That makes sense but then adding new features does not contribute to keep it lightweight. What is the use case for YUV/YIQ?

Mattwmaster58 commented 2 years ago

Understandable. The line between 'lightweight' is sometimes hard to draw. I believe my use case here was a small image comparison library, but I'm not actively working with it at the moment. If you don't want to add this for lightweight/testing concerns I can understand
