This does not seem to work. The compiler error is :
error C2440: '=' : impossible de convertir de 'overloaded-function' en
'boost::function<Signature>'
        with
        [
            Signature=bool (Profile
*,boost::shared_ptr<TTImage<UInt1>>,eInterpolatorType)
        ]

I would like to use boost::bind in order to call ComputeRadiometries with a

Le temps des cerises reviendra. Dans l'immédiat, c'est le temps des noyaux.
Courage.
