Psych.), which was described in Comp. Graphics and Image Processing (1985?..). The original version of this system consists of a large number of image processing routines ( written in C) and features a well thought out image header, which includes an executable history of the operations which have been performed on the given file. The basic system supports typed images ( BYTE, SHORT, INT, FLOAT, DOUBLE, COMPLEX), and image sequences. In regard to some of the other requirements mentioned, we (Computational Neuroscience, NYU MedCtr) have extened the basic HIPS system to include color maps, non-array image formats (histograms, sparse images), arbitrary additional data ( pixel size aspect ratio, and user defined info that needs to accopmany the image), and interactive window based tools for the SUN environment. My impression is that essentially all of the requirements listed are met by the original HIPS implementation and/or our extensions of it. We have used this system for a number of years in a large computer aided neuro-anatomy project, and various computational vision applications: since the basic system is well constructed, it is easy to extend it to handle new problems, although we have found that the current implementation has stabilized, and there is little that we need add...
