Method Detail

getUTF8Text

public String getUTF8Text(int level)

Returns the text string for the current object at the given level.

Parameters:

level - the page iterator level. See TessBaseAPI.PageIteratorLevel.

Returns:

the text string for the current object at the given level.

confidence

public float confidence(int level)

Returns the mean confidence of the current object at the given level. The number should be interpreted as a percent probability (0-100).

Parameters:

level - the page iterator level. See TessBaseAPI.PageIteratorLevel.

Returns:

the mean confidence of the current object at the given level.

getChoicesAndConfidence

public List<Pair<String,Double>> getChoicesAndConfidence(int level)

Returns all possible matching text strings and their confidence level for the current object at the given level.

The default matching text is blank (""). The default confidence level is zero (0.0)

Parameters:

level - the page iterator level. See TessBaseAPI.PageIteratorLevel.

Returns:

A list of pairs with the UTF string and the confidence

delete

public void delete()

Deletes the iterator after use
