Edge Preserving Smooth
This control looks for the most
homogeneous neighborhood area around
each point in a picture, and then gives
each point the average gray level of the
selected neighborhood area. It removes
noise in a flat region without blurring sharp
edges, nor destroying the details of the
boundary of a region. This smoothing also
has the ability to sharpen blurred edges.
Choose either a
Recursive
or the
Normalized Convolution
. By adjusting the
Spatial Sigma
(like the domain) and the
Range Sigma
, you can affect how many
pixels the algorithm uses when applying the smoothing.
