5.1.1. Overview#

This plugin provides several basic filter calculations for itom::dataObject. These filteres are derived from other open-source projects under GPL and hence this plugin is also GPL. These are for instance:

  • despeckle via histogramm and median derived from the GIMP 2.8 despeckle-filter by Michael Sweet

This plugin does not have any unusual dependencies.

These filters are defined in the plugin:

  1. despeckleAdapted()

5.1.2. Filters#

Detailed overview about all defined filters:

itom.algorithms.despeckleAdapted(scrImage, destImage[, lowestValue, highestValue, radius, adapt])#

The filter was implemented based on despeckle filter in gimp 2.8. The filter remove speckle noise from the image This plugin selectively performs a median or adaptive box filter on an image. Michael Sweet <mike@easysw.com>, Copyright 1997-1998 by Michael Sweet
