Hi Guys, I am struggling to display a 16-bit grayscale images from a FLIR tau 2 thermal camera in QT5. I tried different images' encoding and format but the best what I get is like in the right picture and how it should be like in the left one. A part of my code looks like this:
I appreciate any help

Hi and welcome to the forums.
Maybe you could convert it to 8bit with opencv ?

The
cv::normalize(I,I,0.,255.,cv::NORM_MINMAX,CV_8U);
part.

@Khalaf90 You're trying to interpret the image data as 8bit grayscale while it is 16bit grayscale image (I guess that's why right picture looks stretched horizontally :-)). You need to convert it to 8bit first as @mrjj suggested.
