remrx
Removes Reseaus from an image
This program will remove Reseaus from Viking, Voyager, and Mariner images.
The Reseaus are removed using either bilinear interpolation of the
surrounding pixels or by simply putting NULLs in the portion of the
image around the Reseau location of the input image. The ACTION
parameter is used to tell the program which of these two actions to
take. The user should input the size of the box around the Reseau that
will be modified. SDIM and LDIM are the sample and line dimensions of
the box around the reseau. RESVALID is used to determine whether the
program will check the reseau valid flag for nominal reseaux before
removing the reseau. If RESVALID is NO, the program will not check
the reseau valid flag for nominal reseaux and all the reseaux will be
removed except invalid nominal positions. If RESVALID is YES, the
program will check the reseau valid flag that is output from the
findrx program. If the flag is 0, the program will not remove that
reseau. If the flag is 1, the reseau will be removed. If the flag is
-1, indicating an invalid nominal position, the reseau will not be
removed in any case. The output cube file can be written over the
input file or a new output cube can be created. To overwrite the input
file, the TO parameter should be set to blank, " ". The "findrx"
program, which writes the Reseau locations, Reseau type, and a valid
flag to the cube file label, must be run before "remrx".

Parameters
Files
The cube the reseaus will be removed from. All reseaus in the cube
will be removed.
| Type | cube |

Dimensions
The number of samples to remove around each reseau. Defaults to 9.0
| Type | integer |
|---|---|
| Default | 9 |
| Odd | This value must be an odd number |
The number of lines to remove around each reseau. Defaults to 9.0

| Odd | This value must be an odd number |
Options
There are 2 options for removing the Reseaus. The program
can replace pixels inside the SDIM x LDIM box with Null or
bilinear interpolation. Defaults to BILINEAR.

If this parameter is TRUE, the reseau valid flag will be
checked before the reseau is removed. If the reseau
valid flag is a 0 or -1, the reseau will not be removed.
If the reseau valid flag is a 1, the reseau will be
removed. Reseaus with a valid flag=-1 are never removed.
This flag indicates an invalid nominal position.
If RESVALID is FALSE, the reseau valid flag will not be
checked for nominals and all the reseaus will be removed,
except the invalid nominals. Defaults to FALSE.
| Type | boolean |

Example 1
Reseaus replaced with Bilinear Interpolation
This example shows the remrx application with the BILINEAR action option. The SDIM and LDIM default to 9,
and RESVALID defaults to false.
Command Line
Uses bilinear interpolation to fill in missing data around each reseau.
remrx f=../inputRemrx.cub t=out-bilinear.cub
GUI Screenshot
Example Gui
Remrx GuiScreenshot of GUI with parameters filled in to perform a bilinear interpolation remrx operation on the input image.
Input Image
Input image for mirror
Input Io image
Parameter Name:
FROM
This is the 800 by 800 input image for the remrx examples.
Output Image
Output image for bilinear interpolation remrx
Output image showing results of the remrx application with bilinear interpolation option.
Parameter Name:
TO
This is the 800 by 800 output image that results.
Example 2
Reseaus replaced with Nulls
This example shows the remrx application with the NULL action option, using the same input image as the above
example. The SDIM and LDIM default to 9, and RESVALID defaults to false.
Command Line
Nulls out 9x9 boxes around each reseau.
remrx f=../inputRemrx.cub t=out-null.cub
Output Image
Output image for null remrx
Output image showing results of the remrx application with null option.
Parameter Name:
TO
This is the 800 by 800 output image that results.
