clemnirnoise

identifiy and remove NIR noise pattern

WARNING

For the clementine mosaic in Isis2, this program was run before calibration. There is concern this application's systematic noise removal eliminates a substantial amount of valid data.

The program removes a bothersome noise pattern periodically found in Clementine NIR camera imaging. The noise pattern is found in samples 2,6,10,14,18.... found on some or all lines in a NIR image. The program will recognize that the noise pattern exists and then will simply set these sample positions to "null" if the pattern is found.

Example 1

Using clemnirnoise

The use of clemnirnoise detects certain patterns of noise and replaces the noise with nulls.

Command Line

This example shows the use of clemnirnoise to detect and remove systematic noise.
