Method Details

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<Input extends ImageMultiBand<Input>,Middle extends ImageMultiBand<Middle>>

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<Input>,Middle extends ImageMultiBand<Middle>>

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<Input>,Middle extends ImageMultiBand<Middle>>

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<Input>,Middle extends ImageMultiBand<Middle>>

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:

process in interface ImageGradient<Input extends ImageMultiBand<Input>,Middle extends ImageMultiBand<Middle>>

Parameters:
