- Keith;
- I've taken Loren Carpenter's images and made them into a gif file, which
- encludes both the raw data and a filtered or enhanced version of both frames.
- Below are Loren Carpenter's original comments. Maybe you know someone that
- is willing to do the same (create .gif files) of the rest of the frames if
- you could get them from Loren.

- From Loren Carpenter;
-
- >I've been reading the chatter on the net about the "Mars face" for some time.
- >Most, if not nearly all, of the opinions and observations have been based on
- >little or no information. This is largely because of the difficulty of
- >obtaining the original imagery.
-
- >A few years ago when I was with Lucasfilm, I was asked by Mr. Hoagland
- >and associates if I would participate in the "Mars Project". This was
- >to be an informal group of technically capable people who could tinker
- >around with the "face" and "city" pictures in their spare time. Work
- >being what it was, my spare time evaporated and I drifted away from the group.
-
- >However, for the last 5 years I've had Viking Orbiter pictures 35A72 and
- >70A13 on a tape on my shelf. This posting contains the only two images
- >of the "face" returned by Viking. Both images in this posting are
- >100x100 excerpts from 35A72 and 70A13 respectively.
-
- >The data is exactly as I received it. It's pretty noisy and there is an
- >obnoxious riseau mark in one of the images. Most of the noise appears to
- >be caused by "broken bits", i.e. 1 (or maybe 2) bits toggled somewhere
- >in the pixel. I wrote a smart median filter and it cleaned them up fairly
- >well.
-
- >For ease of decoding (everybody doesn't have every spiffy decompressor) each
- >image is encoded in hexadecimal. 4 lines of text constitute 1 scanline of
- >picture. I have also included the file header for each image. It contains
- >camera and sun information, if you can figure it out...
-
- >The original pictures are 1204x1055, so don't expect to see them on the net.
- >Our management won't let other sites log on to ftp files around, so if there
- >is someone who wants to be a librarian, I can probably send them the full
- >files.
-
- >I haven't done anything serious with these images, so please don't flood me
- >with questions. Personally, I think it's just a pile of dirt. The Mars
- >Observer will have 25x the resolution, so hang on a couple of years and
- >we can all see what a pile of dirt looks like up close.
-
- >The excerpts are offset as follows:
- > 35A72: 318 in x, 416 in y
- > 70A13: 152 in x, 874 in y
