Schlagwort: Header

As a follow-up to the previous post, I’d like to present some code which I think might be helpful for other Qt / OpenCV projects as well.

This code was written for Pastie. Pastie is a piece of software I wrote as part my image processing seminar. It makes use of the well known libraries:

• Qt for the graphical user interface
• OpenCV for image processing and computer vision

I wrote a C++ header file to facilitate the co-operation of those two libraries. This file enables the conversion / casting of OpenCV and Qt types e.g.:

#include <QImage>
#include <cv/core.hpp>

QImage qimg("filename.png");
cv::Mat cvimg = toCv(qimg);

The source code is available at GitHub.

The following conversions are supported:

QImage	⇆	cv::Mat
QTransform	⇆	cv::Mat
QPoint	⇆	cv::Point2i
QPointF	⇆	cv::Point2f
QRect	⇆	cv::Rect2i
QRectF	⇆	cv::Rect2f
QSize	⇆	cv::Size

You can find some examples in the real code here and here.
