How to implement CLAHE with Labview

[pkr_111]

Hi everyone,

I want to use clahe method to enhance the image contrast. Unfortunately, there are not any vi about it in NI vision modules.

Searching website info., there is a possible way to do it. That is, build a *.dll file with OpenCV's clahe function by using vc++ language and then call it in labview.

However, it seem to be difficult to me to make the dll file. 

Does anyone has ever done this dll file and can provide me or there are other ways to use the clahe method in Labview?

Thanks.

Hi,

Do you want us to build a algorithm for AHE?

In one of my project I had been thorugh making such algorithm for image improvement and we had created that using VC and OpenCV but unfortunatly I don't have that code.

But yes for reference I used google and NI white papers:

http://www.ni.com/white-paper/3056/en/

http://www.ni.com/white-paper/4877/en/

I hope this will help.

Hi LVKrAkEn,

Thank you for your reply. The CLAHE(Contrast Limited AHE) is a complete function in OpenCV. I can use it in Python.

However, I'm not good in VC. So it is diffcult to me to build the dll with VC.

Although it not solve my issue, still thanks you providing me the transfer method.
