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
