Clean-up application for Mariner10 images

Description

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.

Examples

Example 1

Input Mariner10 Image to be cleaned

Description

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

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