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.

Usage

• Image Volume 1 and Image Volume 2 are two label map images which you wish to load and compare
• The module will provide the DSC and 95% HD between the two images, and will also provide an output volume. The output volume represents the contour of one of the images with each pixel value representing the Hausdorff Distance to the contour of the other image. Both the DSC and 95% HD will be printed onto the Log viewer in Slicer (can be accessed by clicking on the "X" icon that is located at the bottom right hand corner of the Slicer window) and on the Terminal for operating systems other than Windows.
• For improved visualization, the output image should be viewed with a color map. The code provides a color map entitled "Matlab_colormap.txt" which should be used for visualization of the output volume. Change the lower bound of the Threshold in the Display panel of the Volume Module to 0.01.
