                    Planar<D> derivX,
                    Planar<D> derivY)

Description copied from interface: ImageGradient

Computes the image gradient from the input image and stores the results into 'derivX' and 'derivY'

Specified by:

process in interface ImageGradient<Planar<T extends ImageGray>,Planar<D extends ImageGray>>

Parameters:

inputImage - Original input image. Not modified.

derivX - First order image derivative along the x-axis. Modified.

derivY - First order image derivative along the y-axis. Modified.

setBorderType

public void setBorderType(BorderType type)

Description copied from interface: ImageDerivative

Overrides using BorderType.EXTENDED along the image border. Don't change this behavior unless you know what you're doing.

Specified by:

setBorderType in interface ImageDerivative<Planar<T extends ImageGray>,Planar<D extends ImageGray>>

Parameters:

type - Specify image border behavior

getBorderType
