# How does the ImageExposureCombine function work? [closed]

Any ideas for how to find out how this function works?

Combines differently exposed images of the same scene into a single image with overall good exposure.

I'm writing a physics paper that involves this function in some code. I cannot explain how this function works mathematically.

The act of combining differently exposed images seems like a common task in image processing.

If you can point me to a paper that gives a mathematical description of what this function may be doing or if you know of a similar function in an open source language that would help me greatly.

• You will need to ask Wolfram Support. – MarcoB Jun 8 '18 at 14:32
• The code for this function can be inspected using GeneralUtilitiesPrintDefinitions[ImageExposureCombine]`. You will see that it calls the OpenCV function corresponding to the options given, for example MergeRobertson. There are some references given in the OpenCV documentation. – C. E. Jun 8 '18 at 14:33
