2013-12-27 09:56:09 -0500 asked a question copy data to cv::Mat with specific type assigned by the user
cv::Mat A(3, 3, CV_8UC1);
cv::Mat B;
B.create(A.size(), CV_32FC1);
std::cout<<A.type()<<", "<<B.type()<<std::endl;
A.copyTo(B);
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

2013-12-27 05:41:48 -0500 commented question Qt + Android + OpenCV is possible?

I can use other openCV(imgproc, core)modules with Qt on android, but not the camera module of openCV.(Qt5.2.1 would allow us to capture the image buffer from QCamera).

2013-12-27 04:52:49 -0500 asked a question Split contours into many small rectangles

As the graph show, the most easiest solution is return a bounding rect surrounded the contour, split the bounding rect to small rectangles, but it is much harder for irregular shape.What kind of algorithm would you suggest to split the contour?

I would like to implement an algorithm from "Super-Resolution from a Single Image" with the help of openCV.But I don't know I should pay the author patent fee or not, I remember that you have to pay money for some algorithms like z scan.
