hi, is it somehow possible to use the opencv implementation of the CLAHE-algorithm on 16-bit Images? Thanks for your answer.

Hi, I know this is a bit old, but I found this answer when trying to use 16-bit images with OpenCV's CLAHE and wanted to answer for others looking for this. I actually modified the algorithm to accept any integral type.

EDIT: Mainline OpenCV's CLAHE now supports 16-bit images.

@StevenPuttermans - That was me :) I am still in the process of fixing some bugs with it. But hopefully within the next week or so I'll be done.

Mainline OpenCV supports 16-bit images as of today.

is it available in python bindings as well ?

To answer my last comment: yes, it's available for python.

Current implementation supports only 8-bit grayscale images. Code modification is required for 16 bit input.

Hi,

Please check out this link: Result of CLAHE is different on 8 and 16 bit grayscale image.
