These plug-ins provide 3D image filters. Unless otherwise noted, they take a gray scale image of abitrary pixel type as input, process it and return the filtered result as a new image. Filters can be chained by specifying more then one filter description concated with the '+' sign. for example bandpass:min=10,max=20+median:w=3+convert:repn=ushort:map=copy' will create a filter chain that first runs a bandpass, then a median filter and a conversion to unsigned short values by a plain copy.
