opencv Mat与数组之间值传递

1. Mat数据传递给数组
如果Mat数据是连续的，可以直接转换它的数据到一维数组

Mat mat；//方法1，vectorstd::vector<uchar> array(mat.rows*mat.cols);if (mat.isContinuous())    array = mat.data;//方法2，数组unsigned char *array=new unsigned char[mat.rows*mat.cols];if (mat.isContinuous())    array = mat.data;

2. 将数组传递给Mat

unsigned char cbuf[height][width];cv::Mat mat(height, width, CV_8UC1, (unsigned char*)cbuf);
