Return Value

The result of the recognition will have the result of the Master Form Page with maximum confidence. If the confidence is less than MinimumConfidenceKnownForm then null is returned, i.e. the form type is unknown and cannot be recognized.

This method compares the unknown page with all Master Forms pages in the repository and returns the Master Form and the number of the page in that Master Form with maximum confidence.

The recognition of the page will stop comparing the form with other Master Forms either when the confidence of the recognition result is greater or equal to MinimumConfidenceRecognized or when the Master Forms have all been compared.
