About the references

[XuJian1252878]

First, Thank you for providing this focus stacking library.
I am a newcomer to focus stacking, so I have difficulty to understand the focus stacking logic of the source code.
So I want to find the references about the logic for the source code (or which reference is the source code based on).
Can you tell me the references if they are exists?

Hi,
I don't have any references as I did it on my own as it was "homework". It is very simple idea - you pick pixels that seems to be in focus/most sharp. There are more advanced techniques in papers, in code there are some variations of some implementation details that affects results but still the main idea is the same.
Read about blur estimation and edge detectors and you should be able to understand what is going on.
You can start for example with: https://www.pyimagesearch.com/2015/09/07/blur-detection-with-opencv/
