Class OCRBeamSearchDecoder.ClassifierCallback

java.lang.Object

org.bytedeco.javacpp.Pointer

org.bytedeco.opencv.opencv_text.OCRBeamSearchDecoder.ClassifierCallback

All Implemented Interfaces:

AutoCloseable

Enclosing class:

OCRBeamSearchDecoder

public static class OCRBeamSearchDecoder.ClassifierCallback
extends Pointer

\brief Callback with the character classifier is made a class.

This way it hides the feature extractor and the classifier itself, so developers can write their own OCR code.

The default character classifier and feature extractor can be loaded using the utility function loadOCRBeamSearchClassifierCNN with all its parameters provided in .

eval

public void eval(@ByVal
                 Mat image,
                 @StdVector
                 DoubleVector recognition_probabilities,
                 @ByRef
                 IntVector oversegmentation)

\brief The character classifier must return a (ranked list of) class(es) id('s)

Parameters:

image - Input image CV_8UC1 or CV_8UC3 with a single letter.

recognition_probabilities - For each of the N characters found the classifier returns a list with class probabilities for each class.

oversegmentation - The classifier returns a list of N+1 character locations' x-coordinates, including 0 as start-sequence location.
