Detailed Description
Class PreProc defines a preprocessor interface. Preprocessors are transformation functions that don't change the domain of the input features. These functions can be applied in-place if the input features fit in memory or can be applied on-the-fly when (depending on features) a feature caching strategy is applied. However, if the individual features are in
they have to stay in although the dimensionality of the feature vectors is allowed change.As preprocessors might need a certain initialization they may expect that the init() function is called before anything else. The actual preprocessing is feature type dependent and thus coordinated in the sub-classes, cf. e.g. CSimplePreProc .
