Filter menu.
The Mask Size determines the depth of the surrounding pixels that will be
affected. The larger the mask size, the stronger the blurring effect of the
filter.
The Threshold 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.
The Strength specifies the degree of the filter's effect. The higher the
value, the stronger the blurring effect of the filter

Edge Enhancement filter

The Edge Enhancement filter gives greater contrast to edges. The filter can
do this because edges are areas in an image where gray or color levels
change abruptly. It is best to use this tool for improving geometrical
contoured shapes.
