Base class for all exposure compensators.

Methods

virtual
void
apply(
    int index,
    Point corner,
    InputOutputArray image,
    InputArray mask
    ) = 0

Compensate exposure in the specified image.

Parameters:

index	Image index
corner	Image top-left corner
image	Image to process
mask	Image mask

void
feed(
    const std::vector<Point>& corners,
    const std::vector<UMat>& images,
    const std::vector<UMat>& masks
    )

Parameters:

corners	Source image top-left corners
images	Source images
masks	Image masks to update (second value in pair specifies the value which should be used to detect where image is)

virtual
void
feed(
    const std::vector<Point>& corners,
    const std::vector<UMat>& images,
    const std::vector<std::pair<UMat, uchar>>& masks
    ) = 0

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