li. Nip2 workspace
A nip2 ‘workspace’ is a file which holds a set of definitions or software components that adds
specific abilities to the larger software application (a so-called ‘plug-in’), that are used to
carry out a number of transformations on a set of input images. Internally, workspaces are
XML (Extensible Markup Language) files and can be manipulated with the standard XML
tools. Once loaded into nip2 however, they provide an accessible visual framework within
which the nip2 tools carry out their tasks. The modular design and organization of these
workspaces minimise the need for specialised knowledge by the user and reduce user
Subjectivity, since for each imaging method, the relevant fields can simply be filled with the
images required and the transformations can be carried out aided by a set of simple
instructions.
Creation of the workspace to undertake the suite of post-processing transformations
developed within the CHARISMA project was sub-contracted to John Cupitt, one of the
original authors of the nip2 software.
The four workflows as proposed in Figures 1 17-18 and 1 27-28 (see Chapter 1) and
detailed in Table 3-1, have been combined to form this workspace which applies the series
of transformations required to address the correction of a particular type of image (e.g. UVL
images) or class of images (e.g. IRR/UVR images). It has been designed to allow the
correction of individual image sets or a complete set of multispectral images. However, the
post-processing requirements for some workflows may require that previous workflows be
completed prior to running through that workflow, e.g. the workflow for correction of visible¬
reflected images must already have been completed in order to acquire the calibrated
visible-reflected image required for carrying out the workflow for the correction of IR/UV¬
reflected images. In general, the order in which these workflows are described in this
Chapter (and ordered in Table 3-1) is the recommended sequence in which they should be
carried out.
