Class OCRHMMDecoder.ClassifierCallback

java.lang.Object

org.bytedeco.javacpp.Pointer

org.bytedeco.opencv.opencv_text.OCRHMMDecoder.ClassifierCallback

All Implemented Interfaces:

AutoCloseable

Enclosing class:

OCRHMMDecoder

public static class OCRHMMDecoder.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 loadOCRHMMClassifierNM and KNN model provided in .

eval

public void eval(@ByVal
                 Mat image,
                 @ByRef
                 IntVector out_class,
                 @ByRef
                 DoubleVector out_confidence)

\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.

out_class - The classifier returns the character class categorical label, or list of class labels, to which the input image corresponds.

out_confidence - The classifier returns the probability of the input image corresponding to each classes in out_class.
