Need description of the following code :
1 Mat A = imread(argv[1], CV_LOAD_IMAGE_COLOR);
2 Mat F = A.clone();
3 Mat G;
4 A.copyTo(G);
The second line, is the header A is copied to F ?
The forth line, is the header A copied to G or vice versa( G copied to A) ?
Refer to the link to clone and copyTo in the documentation. On line 2, the header A is copied to F and on line 4, A is copied to G.
Mat A = imread(argv[1], CV_LOAD_IMAGE_COLOR);
Mat B = A.clone(); // B is a deep copy of A. (has its own copy of the pixels)
Mat C = A; // C is a shallow copy of A ( rows, cols copied, but shared pixel-pointer )
Mat D; A.copyTo(D); // D is a deep copy of A, like B
Clone will copy the structure of a data where as Copy will copy the complete structure as well as data. More about....Clone Vs Copy
