cv::Mat A(3, 3, CV_8UC1);
cv::Mat B;
B.create(A.size(), CV_32FC1);
std::cout<<A.type()<<", "<<B.type()<<std::endl;
std::cout<<A.type()<<", "<<B.type()<<std::endl;

I want to copy A to B without changing the type of B.

Any clean solution to do this without writing explicit loop?Thanks

ps : I don't want to convert B to CV_32FC1 after copied

Use convertTo method:

A.convertTo(B, B.type());
