GetMinimumRecognizedConfidencePage Method

Summary

Automatically finds the minimum confidence value that is needed to consider an unknown page as recognized and no further Master Form Pages comparison is needed.

Syntax

C++/CLI

Java

Python

public int GetMinimumRecognizedConfidencePage()

public int getMinimumRecognizedConfidencePage();

public: 
int GetMinimumRecognizedConfidencePage();

def GetMinimumRecognizedConfidencePage(self):

Return Value

The minimum confidence value that is needed to consider unknown page is recognized.

Remarks

Automatically finds the minimum confidence value that is needed to consider an unknown page as recognized and no further Master Form Pages comparison is needed.

The comparison is done on the page level.

If the MinimumConfidenceRecognized is set to this value it will speed up the page recognition process without losing the accuracy, by reducing the required number of comparisons

This value is useful when using the RecognizePage(RasterImage,Int32,List<IMasterFormsCategory>) method.
