opencv2 채널분리하기(split)

core.hpp에 선언되어 있는 split을 사용하면 된다.

//! makes multi-channel array out of several single-channel arrays CV_EXPORTS void merge(const Mat* mv, size_t count, OutputArray dst); //! makes multi-channel array out of several single-channel arrays CV_EXPORTS_W void merge(const vector<Mat>& mv, OutputArray dst);      //! copies each plane of a multi-channel array to a dedicated array CV_EXPORTS void split(const Mat& src, Mat* mvbegin); //! copies each plane of a multi-channel array to a dedicated array CV_EXPORTS_W void split(const Mat& m, CV_OUT vector<Mat>& mv);

vector<Mat> 형으로 변수를 선언하여
split(src, dst); 식으로 사용하면 되며
imshow에서 channel[0] 이런식으로 하면 채널별로 출력하면 된다.
