Methods

virtual
void
blend(
    InputOutputArray dst,
    InputOutputArray dst_mask
    )

Blends and returns the final pano.

Parameters:

dst	Final pano
dst_mask	Final pano mask

virtual
void
feed(
    InputArray img,
    InputArray mask,
    Point tl
    )

Processes the image.

Parameters:

img	Source image
mask	Source image mask
tl	Source image top-left corners

virtual
void
prepare(Rect dst_roi)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
