Name
OOF.Image.Modify.Blur — Blur an image by convolving it with a Gaussian operator of the given radius and standard deviation (sigma).
Synopsis
OOF.Image.Modify.Blur(image,radius,sigma)
Details
- Parent Menu: OOF.Image.Modify
-
Callback: function
doImageModin moduleooflib.image.imagemodifier -
Parameters:
image- Type: The path to an existing
Imageobject. radius- Radius of the Gaussian, in pixels, not counting the center pixel. Type: A real number.
sigma- Standard deviation of the Gaussian, in pixels Type: A real number.
Description
Blur the given image. This can be a useful way
of reducing noise, at the obvious expense of a loss of resolution.
The image is convolved with a Gaussian operator with the given
radius and standard deviation
(sigma). For reasonable results, the
radius should be larger than
sigma. If radius is 0,
then a suitable radius will be chosen automatically.
This routine comes from the ImageMagick library.
