apolloremrx

Removes Reseaus from an Apollo image

This program will remove Reseaus from Apollo images. The Reseaus are removed using either PATCH 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. 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 "apollofindrx" program, which writes the Reseau locations, Reseau type, and a valid flag to the cube file label, must be run before "apolloremrx".

Parameters

Files

The cube the reseaus will be removed from.
Type cube
File Mode input
Filter *.cub

The resultant cube containing the data with reseaus removed. (Leave blank to overwrite original)
Type cube
File Mode output
Filter *.cub

Options

The width of the Apollo reseau.
Type integer
Default 5

There are 2 options for removing the Reseaus. The program can replace pixels inside the SDIM x LDIM box with Null or PATCH interpolation. Defaults to PATCH.
Type string
Default PATCH
Option List:
Option Brief Description
PATCH Replace values with PATCH interpolation This option uses PATCH interpolation to create new DN values for the pixels inside the SDIM x LDIM box.
NULL Replace values with NULLs This option will replace each value inside the SDIM x LDIM box with the Isis::NULL value. This allows the user to run another filter program to replace the NULL values.

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
Default FALSE
