Object Detection - Waldboost

In the Extra modules, there is Object Detection using Waldboost.

I tried it and it did not detect anything.

I have read somewhere else, that it is non-working. If so why is it there, without this mention, for this amount of time?.

I have seen some reasearch papers that revolve around the use of Waldboost detector. How did the persons use Waldboost? is there an implmentation somewhere esse ?.

Does anyone know how I can work this ? (step by step)
