mar10clean

Clean-up application for Mariner10 images

Mar10clean performs the clean up of Mariner10 images. This includes salt and pepper noise, removing reseaus, and trimming edges of invalid data. The program runs mar10nonoise to clean up noise followed by findrx and remrx. Several lowpass filters fill in the null areas left by the noise removal. Finally a trim is also completed which nulls the top 5 rows of pixels, left 11 columns pixels, and the bottom 8 rows of pixels.

This program only allows itself to be run once on an image. It is intended for non-compressed images only and will not run on compressed images. Compressed images, technically previously compressed, are distinctive because they are mostly null data with good data in a checkerboard patter, see mar10restore for more info. Mar10clean should be run immediately after importing and before calibration.

Parameters

Files

The cube to be cleaned. The cube will be run through a series of filters to remove salt and pepper noise and reseaus.
Type cube
File Mode input
Filter *.cub

The resultant cube containing the clean data.
Type cube
File Mode output
Filter *.cub

Options

Option to remove or leave intermediate cube files made by the application.
Type boolean
Default TRUE

This number will be used in the remrx step of the clean up. It is the number of samples to remove around each reseau.
Type integer
Default 9

This number will be used in the remrx step of the clean up. It is the number of lines to remove around each reseau.
Type integer
Default 9

Example 1

Input Mariner10 Image to be cleaned

This example shows the application in action. It removes all salt and pepper noise as well as reseaus, and trims invalid data around the edges. The brightness difference visible is caused by different stretchs for each image due to the presence of extreme noise values in the input cube.

Command Line

Input a Mariner10 unclead image to from and output a cleaned image to to.
mar10clean from=MVE_030.227.cub to=clean.cub
