opencv Mat 多通道的使用

代码是8 通道Mat的使用方法。

typedef cv::Vec<float, 8> Vec8f;
E2 = cv::Mat::zeros(srcImage.rows, srcImage.cols, CV_32FC(8));//背景 E(0)值
//CV_32FC3
std::cout << "channel = " << E2.channels() << " \n ";
for (int i = 0; i < E2.rows; i++)
{
for (int j = 0; j < E2.cols; j++)
{
for (int c = 0; c < E2.channels(); c++)
{
std::cout << "channel = " << c << " ";
std::cout << E2.at<Vec8f>(i, j)[c] << " ;i = " << i << " j= " << j << " c= " << c << "\n";
}
}
}
