Only the main branch should result as a result of pruning.

i applied spur operation to this thinned image http://imageshack.us/photo/my-images/194/38936107.png/ and with no. of operation(n) is set to 7, i obtained this image http://imageshack.us/photo/my-images/109/63174203.png/. It can be seen that the main branch also gets removed to some extend.At n=7 only the side branch completely diasappears. as n is increased further main branch starts deteriorating. Is there any other method by which i can remove only the side branch.
