Dear Simon,

Have you checked the ImageScience update site in order to use those
features? As stated in the documentation:

*NOTE*: The features named *Derivatives*, *Laplacian* and *Structure* belong
to the ImageScience <https://imagej.net/ImageScience> suite and need to be
activated by enabling the ImageScience update site in the updater
<http://imagej.net/How_to_follow_a_3rd_party_update_site>.
