[Insight-users] interpretation of the joint histogram in user handbook

[Luis Ibanez]

Hi Xi Liang,

The X and Y axis of the joint histograms shown in figure 8.16
in section 8.5.3 of the ITK Software guide represent the space
of intensity values from the two images shown in figure 8.9.


The image at the left of Figure 8.9 is a T1 MRI image, and
The image at the right is a Proton Density MRI image.



The joint histograms in figure 8.16 is showing:

* The X axis = intensities of the T1 image
* The Y axis = intensities of the Proton Density image.

The range along each axis goes from 0-255.
