将Mat中的内容传递给数组,如果Mat中的数据是连续的,那么对于传递到一维vector我们可以这样: std::vector<uchar>array(mat.rows*mat.cols); if(mat.isContinuous()) array=mat.data; 1. 2. 3. 同样的,传递到一维数组我们可以这样 unsignedchar*array=newunsignedchar[mat.rows*mat.cols]; if(mat.isContinuous(...

6. 注意假设vector是单独一维的话须要转换成Mat才干输出。多维的能够直接输出,比如vector里面存放的是点的话。 #include <iostream> #include <opencv2/core/core.hpp> #include <opencv2/highgui/highgui.hpp> #include <opencv2/imgproc/imgproc.hpp> ...
