    Hey, I don't even know if it will RUN on my computers!

    And probably, in the whole, totally useless compared to what you already
    have in PS.

    A similar image processing system developed at NASA Langley was
    commercialized in Photoflair. The initial releases were crude in that there
    was a gui to a command line program. I haven't looked at it since then. A
    goggle search will get you there.

    That's a good quick headline, but isn't this stuff specifically for
    high-end Solaris/Unix systems? If you are going to post this stuff,
    perhaps a little more investigation as to relevance might be in order..

    The impression that I got from reading the web page was that it
    was in source code form for just about any unix (complete with a "porting
    guide".

    Obviously, faster wider-bus CPUs would benefit it, as would
    high-end graphics cards with hardware support for 3D -- but I suspect
    that with one of the games-optimized graphics cards on a fast Intel based
    unix (OpenBSD, FreeBSD, Linux of one of several forms, etc), you could
    get excellent performance.

    And, FWIW, you can currently download the latest version of
    Sun's Solaris (Solaris 10) for free -- other than the connect time to
    download a DVD-ROM's worth of data (five chunks) plus a CD-ROM's worth
    of data (the "Software Companion" CD for open source programs
    pre-compiled for Solaris). That took me a while, even with a T1 feed. :)

    I am somewhat less certain how useful it would be to most of us,
    but someone needs to try it before we will find out.

    After all -- the "workflow" envisioned here is from slow RF
    links from far distant spacecraft through enhancement and manipulation
    for eventual display. (Think of the information from the Mars Rovers as
    an example.)

    Still -- it would be interesting to see what it can do for the
    likes of us.

    If I had seen a link for downloading it, I would be in that
    process now. However, I am somewhat slowed down by the need to contact
    someone at JPL to get a CD-ROM snail-mailed to me. (And they are
    unlikely to answer a request on Sunday, anyway. :)

    Enjoy,
    DoN.

    There's also IRAF, which is developed literally in the building
    next door to me at this moment, runs on pretty much anything, and
    is doing a fine job for IR astronomy going on here in Tucson.

    And from FORTRAN code -- this is from an earlier version, as the
    Unix version was ported to C from the original FORTRAN used in the VMS
    version.
    And a Word ".doc" file, at that. Good thing that I have
    StarOffice installed. :)
    I wonder what other features it has, which might be more useful
    to us. And I wonder how the C-based version for unix systems differs.

    Enjoy,
    DoN.

    Me too. :) BTW I've been using mandrake 10.1 for a while and love it. Been
    a Linux user since redhat 5.1 days....

    I'm sure some of the docs at the first link explain what it does. It appears
    to be more about dealing with cleaning up MPEG encoded digital video which
    can get pretty ugly!

    No, NASA takes still images, the Hubble has some exposures that are
    days long, one image. There were only a few dozen images from Titan's
    surface (moon of Saturn) done by the Cassini probe.
    The program seems to do everything that a normal image processing
    program does, and it can also generate stereoscopic image pairs, which
    is a bit of a novelty.

    Since we're churning through open source image processing libraries...
    There's VIPS/NIP which is being used by museums to process
    super-high-rez IR scans of priceless paintings and stuff like that.

    I wrote a fink (Mac OS X) installer for it a year back or so, to try it
    out, and it's pretty interesting. As they say, Photoshop-meets-Excel is
    exactly right. The newer version supports 16-bit and colorspace
    management, which might have interesting implications for RAW
    processing.

    <http://www.vips.ecs.soton.ac.uk/>

    What is it?

    VIPS is a free image processing system. It aims to be about half-way
    between Photoshop and Excel: it is very bad at retouching photographs,
    but very handy for the many other imaging tasks that programs like
    Photoshop get used for. It is good with large images (images larger than
    the amount of RAM in your machine), and for working with colour.

    Solaris 10 on an Ultra-2 with Creator-3D card at the moment.
    I've been using Suns since the 2/120 (my first Sun machine), and gone
    through the migration from 68010 (Sun-2) through 68020 (Sun-3), and
    quite a few of the SPARC (sun4, sun4c, sun4m, sun4u) machines -- as they
    got old enough to be really affordable. :)

    Lots of other boxen as well, including several of the AT&T
    UnixPC, which was a fun box also based on the 68010.

    I started into unix-like OSs with Microware's OS-9 for the 6809.
    Yep -- and they can't simply re-shoot, with what they are
    getting and from *where* they are getting it. :)

    But it still might have something useful in it.

    Enjoy,
    DoN.

    Note the line at the bottom:

    "Document Review: CL 96-0842 on 22-May-96 by Charlotte Marsh"

    This is really old stuff; they don't even seem to have a download
    site, as they figured back in '96 that you would order the CD-ROM.

    Makes me wonder if they've upgraded what they use. It would seem
    likely.
