Convert Mat to 16 bit int

Hi,

I want to convert my 16 bit images from format cv::Mat to 16 bit. Currently, I am using this function

int size = image.total() * image.elemSize(); // number of elements * size of elements
float * bytes = new float[size];  
std::memcpy(bytes, &image.data, size * sizeof(float));
return bytes;

which only allows me to use 8 bit images (format bytes). Do you know a function call to convert cv::Mat to my desired bit format?

Best

aww dear, code above is all wrong (why float? size is also already in bytes)

can't you just use mat1.convertTo(mat2, CV_16U)

I want to use the data of cv::Mat in CUDA, and CUDA does not support cv::Mat. So, using mat1.convertTo(mat2, CV_16U) wouldnt be helpful.

wait, i probably misread it. are those Mat's 16bit already ?

you could still get ushort*ps = mat.ptr<ushort>()

Yes, they are 16 bit.

ah, ok, does not need any conversion , then (my bad)
