| The image below on the left shows the false colour rendering of the data file Lunar Lake. Each image cube is split into a number of scenes for delivery purposes. Here we see all the three scenes of the image. However we will be presenting statistics of the first scene (top 1/3 of the image on the left). | ||

The figure on the left shows the correlation coefficients between the 224 bands. As can be seen, the bands in the range 155 to 165 have a low correlation coefficient ~ 0.1 to 0.6. The same is true for the bands in the range 108 to 112 where the correlation coefficients are around 0.4 to 0.7. This means that predicting a band within this range from pervious bands will not be effictive. |

Here we consider the correlation coefficients between the the 512 lines. As opposed to the previous scale where the range was [0.0 1.0], the range here is ~ [0.94 1.0] which means that there is significantly higher correlation from line to line than from band to band. On close observation we find that the plot exhibits an unusual texture: lines show higher correlation with the alternate lines as opposed to adjacent lines. | |
|
Column correlation coefficients are similar to the bands but only higher correlation since the scale is approx. [0.92 1.0]. | |
