PSFILT - Mariner 9 Pinstripe Filter
PROGRAMMER:  MARS1::KEH (Ken Herkenhoff, Caltech)
This procedure finds and removes pinstripes in Mariner 9 images, as
documented in M9PSR.  The input image must be 16-bit; the output image
will also be 16-bit.  FLT16B is used to create two low-pass filtered
versions of the input image:  1 x 25 pixels and 7 x 25 pixels.  M9PSR is
used to find the difference between the two filtered versions and
subtract the difference from the input image.  See M9PSR.PDF.
This procedure runs the following programs:  BOXFILTER, M9PSR.

ADDITIONAL NOTES:

ParmDescription
FROM
The Mariner 9 input image file must be 16-bit, and is usually
the result of level 1 processing. The image must NOT have
been geometrically transformed in any way. Do NOT include the
extension with the filename. The program will assume .cub as
the filename extension.
TO
The output image will also be 16-bit, with pinstripe noise
removed. If the file extension is omitted, then ".cub" will
be assumed.
