[gdal-dev] Looking for some gdal-python-math-stuff help: HighLightCompressVisualizer

[Stefan Gofferje]

Hi all,

I'm still tinkering on my 
automatic-download-satellite-data-and-create-images-from-my-area scripts 
and I was wondering if anybody could help me out or point me to some math.

I'm currently using percentiles in a little Python script to compress 
the contrast of my images. The result is pretty OK but it breaks if 
large areas of the image are very bright, like clouds or snow.

The Sentinelhub EO Browser offers a function HighlightCompressVisualizer 
(see 
https://docs.sentinel-hub.com/api/latest/evalscript/functions/#highlightcompressvisualizer) 
which does that "a little" better.

Is there anything comparable in gdal, python or any related library?
That level of math is a little bit above me. High school was long ago...

T:Stefan
