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.
Parm | Description | Default |

ADDITIONAL NOTES:
Parm | Description |
---|---|
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. |
