OpenCV function to convert 8U image to 16U

开发者_如何学运维Is anyone aware of any functions in OpenCV which support 8U to 16U conversion? I tried cvConvertImage, cvConvertScale but they are all meant to operate only on 8U image formats.

If you're using the newer C++ API, then check out Mat::convertTo

Mat a(rows, cols, CV_8U);
Mat b;
a.convertTo(b, CV_16U);
