The online documentation has many tutorials. Here are some notes of small problems that I encountered, since the tutorials are not designed for OpenCV3.0.
1) Load, modify, and save an image: Be sure to add headers "core", "imgproc", and "highgui", so that the preamble looks like:
#include <opencv2/core/core.hpp>
#include <opencv2/highgui/highgui.hpp>
#include <opencv2/imgproc/imgproc.hpp>
#include <cv.h>
#include <highgui.h>
#include <iostream>
using namespace cv;
2) In the Mat example, be sure to account for OpenCV 3's change to the format function.
cout << "R (python) = " << endl << format(R,Formatter::FMT_PYTHON) << endl << endl;
cout << "R (csv) = " << endl << format(R,Formatter::FMT_CSV) << endl << endl;
