mar10nonoise

Noise removal from Mariner10 images

This program will remove noise from Mariner10 images. The program works by running noisefilters for high noise and then low noise repeatedly. Any data that is determined to be noise is set to null. Some noise may be left over and it is possible that good data can be picked up, however, this should be a very small precentage. Further filtering can be achieved with the noisefilter application.

Mar10nonoise is meant for uncompressed Mariner10 images only and will not be effective in removing noise from previously compressed images. See mar10restore for more on these images.

Mar10nonoise is executed in the pipeline performed by mar10clean and shouldn't be necessary to be run when processing Mariner10 images if using mar10clean.

Example 1

Input Mariner10 Image to have noise removed

This example shows the application in action. It removes most noise. Noise is replaced with null data. The brightness difference visible is due to a difference in stretches between the two images due to the noise in the first.

Command Line

An example of an uncleaned Mariner10 image for input and a noise removed output cube.
mar10nonoise from=MVE_030.227.cub to=nonoise.cub
