Compatibility with OpenCV 4
Changes to make OTB compatible with OpenCV 4. The SuperBuild OpenCV version has been upgraded to v4.1.1
This MR doesn't remove compatibility with open CV 2, but maybe we should drop it, see issue #1954.
OpenCV 4 has been released, we need to make OTB compatible with it !
The main change of OpenCV4 is the use of C++ 11.
The SuperBuild code has been modified to use open cv 4.1.1. The OpenCV patch has been updated.
OTB_OPENCV_4 cmake variable has been defined and is true when the openCV major version number is 4.
OTB_OPENCV_3 is true for both openCV 3 and openCV 4.
The neural network machine learning model has been updated to use
cv::Mat instead of the c class
CvMat (deprecated since open cv 2...). In OpenCV4
CvMat can't be serialized easily, which is an issue when saving/loading the model.
The GetVote method of
CvRTreeWrapper has been implemented, as it is pure virtual in opencv4.
