'Change OpenCV float image default palette range from [0 1] to some custom [min max]

Is it possible to change OpenCV float image default palette range from [0 1] to a custom [min max]?

Mat img(h, w, CV_32FC1); // Create float image
DoStuff(img); // Fill data
ChangePaletteMinMax(img); // Is it possible to change the default palette? Or I need to normalize it to [0 1] ?
imshow("My float image", img); // The greyscale is only from 0 to 1.

You can use normalize() to set your custom range:

normalize(img, dst, 0, 255, NORM_MINMAX, CV_8UC1)

In the above, the range has been set to 0 - 255.

I think your network firewall not support STUN ( udp hole punching ) so you have to add turn server address to your iceConfiguration.
