Codebook-based background subtraction using kohonen

Hello !

I'm looking for an efficient background subtraction method. I've tried
the Mixture  of Gaussians (MOG) and i've found a paper by Kim, Harwood
and Davis, named :
A perturbation method for evaluating background subtraction algorithm.

In this paper the author test several background segmentation methods
and concluded that the method they have implemented is the best.
Their method is a quantization/clustering method to construct a
background model using kohonen.

Since i don't have a lot of time to spend implementing this method, i
would like to know where i could find a public source code (C/C++) of
this algorithm.

Any help, links or suggestion would be welcomed.

thx
