// 0 1 0
// 1 -4 1
// 0 1 0
Mat PoissonBlending::getLaplacian()
{
Mat lap = Mat::zeros(3, 3, CV_32FC1);
lap.ATF(0, 1) = 1.0;
lap.ATF(1, 0) = 1.0;
lap.ATF(1, 2) = 1.0;
lap.ATF(2, 1) = 1.0;
lap.ATF(1, 1) = -4.0;
return lap;
}示例2: getA
// get Matrix A.
Mat PoissonBlending::getA(Mat &roiMask,vector<Point> &Points)
{
