Review of Moore Neighbour Tracing

expertise: 3 sensitivity: 5 
Summary:
The author implements the moore neighbour tracing algorithm in order to produce an ordered list of the outline of a 2D blob or a contour presented as an image.
Hypothesis:The author's code has a number of examples, including a dummy square that is produced and then operated on by the algorithm to produce a working result. The author allows user files to be run on the algorithm also.
For the example that displays the ordered boundary element list as a color map from black through white using the 'hot' colourmap there is an assumption based on the datatype of itk::Image that is passed in that there will be up to 255 boundary elements, otherwise the colormap will be repeated.
Evidence:Evidence is shown in the examples of the algorithm running correctly. From brief observation it seems to run fine.
Open Science:The code is able to viewed, extended and the examples are also available.
Reproducibility:Code ran successfully for me using CMake 2.8 and Visual Studio 2008.
