 Mat rowPaddedImage(src.size(), CV_64F, Scalar(0, 0, 0));
copyMakeBorder(double_src, rowPaddedImage, 0, 0, left, right, BORDER_CONSTANT, value);

Comments

delete nothing. Mat is a shared ptr : don't worry about memory management

you NEVER use new or delete here.

Mat m(H,W,sometype);

will allocate data

m.release(); // called automatically at end of scope

will deallocate it

Thank you!
