Hi Laurenz,

Maybe you could try enabling the Low/High Clipping.

I am not 100% sure if it will work but at least it is something to try.

Cheers,

Hi,

I'm having some trouble with the background subtraction in the
NDPluginProcess and UInt16 data type. Whenever the values would turn
negative due to the background subtraction, the UInt16 wraps around and
produces values close to 65536. What is the best way to avoid this this?

Thanks, Laurenz
