This parameter specifies the
degree of the filter's effect. The
higher the value, the stronger is
the blurring effect of the filter.
This parameter allows you to
specify a tolerance range or a
field of contrast between
adjacent pixels before blurring
is applied. Blurring is applied
only when pixel differences are
below the Threshold value. The
smaller the Threshold value, the
weaker the blurring effect.
This parameter
determines the depth of
the surrounding pixels
that will be affected. The
larger the mask size, the
stronger the blurring
effect of the filter.

Gaussian Blur filter
The Gaussian Blur is used to blur or defocus an area of the image where
significant color transitions occur or where noise exists, and the filter produces
a hazy effect. “Gaussian” refers to the bell-shaped curve that is generated when
this filter adjusts the color values of the affected pixels. The dialog box below
appears when you choose Gaussian Blur from the Filters menu.
