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 visiblereflected 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/UVreflected 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.
