3.2.6 Gaussian Variance

<gaussian_variance></gaussian_variance>

  • 0.3333

This option is only active if the "smoothing" option is turned on AND the "smoothing_algorithm" is set to "gaussian". It is a floating point value.

The height and width of the Gaussian kernel depends on this variance by the formula:

width= 2* ceil( 3*gaussian_variance) +1

Therefore, with the default value, the height and width of the kernel would be 3.
