 Although the first figure shows four steps in erosion, it took 7 steps in order to make them totally separate. The ball structuring element with radius 5 was used in erosion process.
-The last figure shows the different results by using three different structuring elements:neighborhood, ball, cross in order. It can be observed that the shape is better when ball structuring element is used compared to cases of using either neighborhood or cross structuring element.

 ===The Problems===
-In this module, the problems were stemmed from the choices of structuring element, the radius size of them. The performance of erosion depends on the properties of structuring element. The reason is that sometimes the shape of the binary image can not be preserved after erosion. For instance, the spheres data I used became had like a square shape if I used other structuring elements instead of ball structuring element. Therefore, ball structuring element was used in BinaryErodeOperations Module. However, if user wants to try others, the default value for structuring element should be changed from the code file. I could not also do it interactive.

I could not also do it interactive. The difference between the performance of structuring elements can be seen in ''Screen shots'' section.
-In addition to the problems, I encountered with a problem when I used binary labeled image as an input to BinaryErodeOperations Module. The problem is that I could not create a label map by using Editor Module in Slicer 3. The reason may be due to the output I have after LabelBinaryImages Module. The inside pixel is 1 and the outside pixel is 0 for the binary labeled images. The erosion worked well these images but at the end of the erosion' I could not define two different labels by using Editor Module. Therefore, without having different labels, I could not continue on dilation because in dilation my aim is to see different labeled images touched each other but not overwritten after several steps. However, the failure in creating labels is the reason of not using the binary labeled images for my project. The detailed information is given in the section of ''the Problems'' in [[Slicer3:Module:LabelBinaryImages-Documentation|LabelBinaryImages]].
