public int GetMinimumRecognizedConfidenceForm()
The minimum confidence value that is needed to consider unknown form as recognized.
Automatically finds the minimum confidence value that is needed to consider an unknown form is recognized and no further Master Form comparison is needed.
If the MinimumConfidenceRecognized is set to this value it will speed up the form recognition process without losing the accuracy, by reducing the number of required comparisons.
If RecognizeFirstPageOnly is set to true, this value will be calculated based on the first page of the Master Forms, otherwise it will use all Master Forms pages.
This value is useful when using the RecognizeForm(RasterImage,List<IMasterFormsCategory>) method.
