processing laboratory s image processing system michael landy co wrote and sell a general purpose package for image processing which has been used for basically all the usual image processing applications robotics medical satellite engineering oil exploration etc it is called hips and deals with sequences of multiband images in the same way it deals with single images it has been growing since we first wrote it both by additions from us as well as a huge user contributed library feature description hips is a set of image processing modules which together provide a powerful suite of tools for those interested in research system development and teaching it handles sequences of images movies in precisely the same manner as single frames programs and subroutines have been developed for simple image transformations filtering convolution fourier and other transform processing edge detection and line drawing manipulation digital image compression and transmission methods noise generation and image statistics computation over such image transformation programs have been developed as a result almost any image processing task can be performed quickly and conveniently additionally hips allows users to easily integrate their own custom routines new users become effective using hips on their first day hips features images that are self documenting each image stored in the system contains a history of the transformations that have been applied to that image hips includes a small set of subroutines which primarily deals with a standardized image sequence header and a large library of image transformation tools in the form of unix filters it comes complete with source code on line manual pages and on line documentation host configuration requirements originally developed at new york university hips now represents one of the most extensive and flexible vision and image processing environments currently available it runs under the unix operating system it is modular and flexible provides automatic documentation of its actions and is almost entirely independent of special equipment hips is now in use on a variety of computers including vax and microvax sun apollo masscomp ncr tower iris ibm at etc for image display and input drivers are supplied for the grinnell and adage ikonas image processors and the sun sun sun and sun i consoles we also supply user contributed drivers for a number of other framestores and windowing packages sun gfx sun console matrox vip iti ip lexidata macintosh ii x windowing system and iris the hipsaddon package includes an interface for the crs it is a simple matter to interface hips with other frame stores and we can put interested users in touch with users who have interfaced hips with the arlunya and datacube max video hips can be easily adapted for other image display devices because of hips is machine independent availability hips has proven itself a highly flexible system both as an interactive research tool and for more production oriented tasks it is both easy to use and quickly adapted and extended to new uses hips is supplied on magnetic tape in unix tar format either reel to
