4. Data Structure
Data in GIPSY is stored in so called sets . A set consists of two components: an image component and a descriptor component. These components are stored in separate files, but in GIPSY they are always used together. The image data is stored in a `crystalline' structure with a virtually unlimited (up to 20) number of dimensions. ... Within a set subsets can be defined. ... The figure below shows the possible subset types in a three-dimensional set, a `` cube '': . ...
