signatures for the emd function

edit

Hello, I'm currently using the opencv library version 2.4.10 and I'm a new user. Can anyone give me a C++ example for creating signatures [i.e., convert histograms into signatures] for the emd function? I have read through the tutorial and reference manuals that came with the package I have but I couldn't find any examples for this. I found an example for the old 1.0 version library but had no success trying to convert it over to the new version I have. Thank you in advance for your help, WJS
