 ===Module Description===
-This module is capable of calculating the 95% Hausdorff distance (HD) and the Dice Similarity Coefficient (DSC) between two label map images. If the two label map images represent registered segmented structures then the 95% HD and DSC will provide a measure of contour and volumetric alignment between the images. These two metrics are explained in detail in the References section.
+This module is capable of calculating the 95% Hausdorff distance (HD) and the Dice Similarity Coefficient (DSC) between two label map images. If the two label map images represent registered segmented structures then the 95% HD and DSC will provide a measure of contour and volumetric alignment between the images. The HD is the maximum distance of a set to the nearest point in another set and gives a measure of contour alignment between structures. The DSC gives a measure of the volumetric overlap between the two segmented structures, and indicates twice the number of voxels which are shared by or are common to both structures divided by the total number of non-zero voxels in both structures. The DSC can range from zero to one, where zero is no alignment between images and one is perfect alignment. These two metrics are explained more formally in papers presented in the References section.

 * Change threshold to "manual" and make the lower bound of the interval 0.01. Change the Window/Level to make the output volume take on the range of colors from blue to red.
 * The red pixels represent the pixels that have the highest HD with respect to the contour of the other input image. The pixel value shows the HD. This shows which part of the contour is further away (i.e. have highest grade of misalignment) from the contour of the other input image.
