Module Description

Convolves the image with a Gaussian kernel wherein the Gaussian has a standard deviation specified by the user (GUI field "sigma") and the kernel width in each dimension is 6 times the standard deviation of the Gaussian.-


Input volume = <grayscale image>
Output volume = <new image>
Sigma = <std dev of gaussian for convolution>

Examples, Use Cases & Tutorials

  • Use to reduce noise

Quick Tour of Features and Use

  • Set the sigma value to control the amount of blur. Larger sigma = more blur.
