Opencv Mat 6种输出格式

Opencv Mat 6种输出格式分别是：默认、Matlab、Csv、Python、Numpy、C。

6种输出格式枚举定义。

enum { FMT_DEFAULT = 0,

FMT_MATLAB = 1,

FMT_CSV = 2,

FMT_PYTHON = 3,

FMT_NUMPY = 4,

FMT_C = 5

};

Opencv Mat 6种输出格式测试代码：

#include <iostream>

#include <opencv2/opencv.hpp>//opencv的头文件

using namespace std;

using namespace cv;

int main()

{

Mat array(10, 3, CV_8UC3);

randu(array, Scalar::all(0), Scalar::all(255));

cout << "【默认风格】" << endl << array << endl << endl;

cout << "【Python风格】" << endl << format(array, Formatter::FMT_PYTHON) << endl << endl;

cout << "【逗号分隔风格】" << endl << format(array, Formatter::FMT_CSV) << endl << endl;

cout << "【Numpy风格】" << endl << format(array, Formatter::FMT_NUMPY) << endl << endl;

cout << "【C语言风格】" << endl << format(array, Formatter::FMT_C) << endl << endl;

return 0;

}
