Detailed Description

ImageViz 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:
