public Image run(Image image, double scale)
image
- The input image for which the Laplacian needs to be computed. If it is of type FloatImage
, it will be used to store intermediate results. Otherwise it will be left unaltered. If the size of the image in the z-dimension equals 1
, this method will compute, for every image element, the two-dimensional (2D) Laplacian. Otherwise it will compute for every image element the full three-dimensional (3D) Laplacian. These computations are performed on every x-y(-z) subimage in a 5D image.scale
- The smoothing scale at which the required image derivatives are computed. The scale is equal to the standard deviation of the Gaussian kernel used for differentiation and must be larger than 0
. In order to enforce physical isotropy, for each dimension, the scale is divided by the size of the image elements (aspect ratio) in that dimension.
FloatImage
.
java.lang.IllegalArgumentException
- If scale
is less than or equal to 0
.
java.lang.IllegalStateException
- If the size of the image elements (aspect ratio) is less than or equal to 0
in the x-, y-, or z-dimension.
java.lang.NullPointerException
- If image
is null
