opencv Mat 多通道的使用

代码是8 通道Mat的使用方法。

	typedef cv::Vec 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(i, j)[c] << " ;i = " << i << " j= " << j << " c= " << c << "\n";
			}
		}
	}
