c++ - How to initialize contour in OpenCV in C++

Question

I want to use drawContours function in O

 vector<vector<Point> > contours;

How to assign the following (x,y) to the variable contours?

x = [194, 253, 293, 245]
y = [72, 14, 76, 125]

Can anyone help me out??

Answer 1

contoursC++11 では、ベクターを簡単に初期化できます。

vector<vector<Point>> contours = {{{194, 72}, {253, 14}, {293, 76}, {245, 125}}};

contoursは等高線の であることに注意してください。vectorここで、各等高線はvector<Point>です。つまり、ポイントのコンテナーのコンテナーです。

Answer 2

Is this code can help you ?

vector<Point> firstContour;
firstContour.push_back(Point(194,72));
firstContour.push_back(Point(253,14));
firstContour.push_back(Point(293,76));
firstContour.push_back(Point(245,125));
contours.push_back(firstContour);
