OpenCV function 将8U图像转换为16U

Question

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.

Answer 1

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);
