Hello, I managed to load an IR image captured by an IR camera with a legacy format. I manage to see the image which are with a very poor contrast (almost grey, but something can be seen). I tried to save the image in a bmp format (imwrite("filename.bmp", image_IR)) but the resulting image is completely white.

Does anybody have any suggestion?

The image is white because it is stored as 8 bit image. I guess values in your 16 bit image are bigger than 255. You should first convert your image to 8 bit with appropriate scaling (1/256.0) by calling to convertTo function.
