To be compilable with early version of OpenCV

Compile the code in my machine will cause some errors like:
```
g++ examples/seg/createFinalRes.cpp -pthread -fPIC -DNDEBUG -O2 -I/usr/include/python2.7 -I/usr/lib/python2.7/dist-packages/numpy/core/include -I/usr/local/include -I.build_release/src -I./src -I./include -I/usr/local/cuda/include -Wall -Wno-sign-compare -c -o .build_release/examples/seg/createFinalRes.o 2> .build_release/examples/seg/createFinalRes.o.warnings.txt \
		|| (cat .build_release/examples/seg/createFinalRes.o.warnings.txt; exit 1)
examples/seg/createFinalRes.cpp: In function ‘int main(int, char**)’:
examples/seg/createFinalRes.cpp:70:63: error: no matching function for call to ‘cv::Mat::copyTo(cv::Mat)’
examples/seg/createFinalRes.cpp:70:63: note: candidates are:
/usr/include/opencv2/core/core.hpp:1651:10: note: void cv::Mat::copyTo(cv::OutputArray) const
/usr/include/opencv2/core/core.hpp:1651:10: note:   no known conversion for argument 1 from ‘cv::Mat’ to ‘cv::OutputArray {aka const cv::_OutputArray&}’
/usr/include/opencv2/core/core.hpp:1653:10: note: void cv::Mat::copyTo(cv::OutputArray, cv::InputArray) const
/usr/include/opencv2/core/core.hpp:1653:10: note:   candidate expects 2 arguments, 1 provided
make: *** [.build_release/examples/seg/createFinalRes.o] Error 1
```
But it can fixed after a litte modifications of code like: http://stackoverflow.com/questions/10481411/opencv-copy-an-cvmat-inside-a-roi-of-another
