public Image gauss(Image image, double scale)
image
- The input image to be smoothed. If it is of type FloatImage
, it will be overwritten with the smoothing results. Otherwise it will be left unaltered. The algorithm is applied to every x-y(-z) subimage in a 5D image.scale
- The smoothing scale at which derivatives are computed. The scale is equal to the standard deviation of the Gaussian smoothing kernel 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
. If the input image is also of that type, the returned image is the same object, overwritten with the smoothing results.
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
.
