Specified by:

setBorderType in interface ImageDerivative<Input extends ImageMultiBand,Output extends ImageGray>

Parameters:

type - Specify image border behavior

getBorderType

public BorderType getBorderType()

Description copied from interface: ImageDerivative

Returns how the image borders are handled.

Specified by:

getBorderType in interface ImageDerivative<Input extends ImageMultiBand,Output extends ImageGray>

Returns:

Image border type.

getBorder

public int getBorder()

Description copied from interface: ImageDerivative

How many pixels wide is the region that is not processed along the outside border of the image.

Specified by:

getBorder in interface ImageDerivative<Input extends ImageMultiBand,Output extends ImageGray>

Returns:

number of pixels.

getDerivativeType

public ImageType<Output> getDerivativeType()

Description copied from interface: ImageDerivative

Image type for derivative output

Specified by:

getDerivativeType in interface ImageDerivative<Input extends ImageMultiBand,Output extends ImageGray>

process

public void process(Input inputImage,
                    Output derivX,
                    Output derivY)

Description copied from interface: ImageGradient

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

Specified by:
