findContours(imgBinary, allContours, hierarchy, CV_RETR_TREE, CV_CHAIN_APPROX_SIMPLE, Point(0, 0));

I haved the allContours, and Matrix of Perspective and Affine Transformation

How do contours Perspective(2D) and Affine Transformation???

Which function use???

Use direct "perspectiveTransform", have error

vector<vector<Point> >contours1;
perspectiveTransform(allContours1_fin, perspectiveTransform(allContours, contours1, H1I);
H);
