The technique, known as decorrelation stretch, is used to enhance contrasts in digital imagery. It was first developed by researchers at NASA’s Jet Propulsion Laboratory (JPL) in 1978 to improve the interpretation of high-correlation remote sensing and satellite imagery.

This looks like an advert for Dstretch.

This seems to be an open source alternative https://github.com/BenDyson-Arch/LDCS

That's really cool! In a time where every "enhancement" is AI guessing there's something really pure and satisfying about an algorithm like this.
