mar10restore

Restoration of Mariner10 compress images

This application makes full images out of previously compressed images. Mar10restore will only run on previously compressed images. A previously compressed image is distinctive because it is 3/4s null data, with good data in a sort of checker board pattern. The compressed images may appear dark until zoomed in on. By removing noise and then averaging the good data, a decent image can be produced.

Mar10restore provides similar functionality to mar10clean, except for previously compressed images. The steps are, noise removal with noisefilter, averaging with lowpass, and a trim for bad data around the edges. Reseaus are lost, between the loss in the compression and the noise filtering, they are not visible or removed and so cannot be found, or directly removed. Mar10restore should be used in the same way mar10clean is used, it should only be run once and used before calibration.

Example 1

Input Mariner10 image to be restored

This image was originally transmitted compressed and now needs to be restored. Restoration is imperfect as only a quarter of the original data is present.
