public class SoNagaoFilterProcessing2d
extends SoImageVizEngine

SoNagaoFilterProcessing2d engine The SoNagaoFilterProcessing2d engine computes a mean neighbors value around a central pixel.

For an introduction to image filters, see section Images Filters.

This engine uses an adaptive 5x5 neighborhood geometry to compute a mean neighbors value around a central pixel. For each pixel, the used geometry is selected, among a predefined set, with respect to a minimum variance criterion. User can optionally switch this criterion to a minimum range criterion.

Four neighborhood geometry types are supported by this filter:

• The Tsuji-Tomita neighborhoods: a set of five 3x3 sub neighborhoods among the 5x5 main neighborhoods.
• The Nagao neighborhood with a set of nine 7 pixels sub neighborhoods among the 5x5 main neighborhoods:
• The Nagao neighborhood with a set of nine 9 pixels sub neighborhoods among the 5x5 main neighborhoods:
• The Nagmod neighborhood: a set of nine 3x3 sub neighborhoods among the 5x5 main neighborhoods See also:

SoBilateralFilterProcessing, SoSigmaFilterProcessing, SoUnsharpMaskingProcessing.
