XPLORE is an exploratory image processing system, namely a collection of computational tools which have been found useful in the design of image processing operations. The system is one of (mainly) ANSI FORTRAN subroutines to accept, process and display images on the PDP-11/40, a general purpose mini-computer. XPLORE can be used as it stands to carry out various display and transform operations, and extra facilities can be readily inserted by any user willing to learn about a very small number of utility subroutines. The sub-routines of the system can be used independently if the user wishes. The facilities available include window selection, histogramming, image transformations, creation of marginal totals and manipulation of image information expressed in curvilinear form. The system is portable, convenient to use and as fast as can reasonably be expected of one which relies on disc storage and calculation at mini-computer speeds.
