I am trying to reduce the highlights in an image caused by a high intensity light source. I tried various softwares and I found that "Highlight Reduction" works for me. But I am not able to understand the actual processing behind a Highlight Reduction. Can anybody please help me regarding that ?

You're going to have to give us more information. Is "Highlight Reduction" a program? (if so, add at least a link) Or is it an option in a program? (if so, which program?) – Cris Luengo Jul 02 '18 at 05:28

I have tried this in almost all major Image edition softwares. Naming a few would be Adobe Lightroom, Snapseed for Android. – pr22 Jul 02 '18 at 05:36

So you're assuming they all do the same thing? – Cris Luengo Jul 02 '18 at 05:38

They all have a highlight adjustment option. And I want to know what exactly is happening in that highlight adjustment option. – pr22 Jul 02 '18 at 05:40

What I'm saying is that it's unlikely that any of these programs implement the same thing for highlight reduction. The name of the option might match, but it's not a standardized algorithm, and so what actually happens to the image will be different for different programs. – Cris Luengo Jul 02 '18 at 05:43

But they may follow certain basic algorithm right. I want to know what is that algorithm ? – pr22 Jul 02 '18 at 05:45

Your question is far too vague and broad for Stack Overflow. You also don't even show any sample images nor are you specific about what you have tried. – Mark Setchell Jul 02 '18 at 07:33

Perhaps http://answers.opencv.org/question/92887/specular-highlights-detection/ may give some hints. At least 3 papers are cited there:
Searching around the literature I found the following 3 interesting papers: Real-time highlight removal using intensity ratio, Efficient and Robust Specular Highlight Removal and Fast and High Quality Highlight Removal from A Single Image. The first two that they provide the code as well gave not that good results.
