I would like to display a 16-bit grayscale images from a thermal camera in OpenCV. I tried different images' encoding but what I get is either totally black or totally white picture. my code looks like this:

void imageCallback(const sensor_msgs::ImageConstPtr& img)
{
             cv_bridge::CvImagePtr cv_ptr;
             cv_ptr = cv_bridge::toCvCopy(img);
             cv::imshow("16-bit Mono", cv_ptr->image);
             cv::waitKey(1);
}

in case that someone face the same problem in the future, the solution is to convert from 16 bit to 8 bit per pixel usin
