Member Function Documentation

static Ptr<NormalBayesClassifier> cv::ml::NormalBayesClassifier::create ( )

static

Python:
	retval	=	cv.ml.NormalBayesClassifier_create(		)

Creates empty model

Use StatModel::train to train the model after creation.

static Ptr<NormalBayesClassifier> cv::ml::NormalBayesClassifier::load ( const String &  filepath, const String &  nodeName = String()  )

static

Python:
	retval	=	cv.ml.NormalBayesClassifier_load(	filepath[, nodeName]	)

Loads and creates a serialized NormalBayesClassifier from a file.

Use NormalBayesClassifier::save to serialize and store an NormalBayesClassifier to disk. Load the NormalBayesClassifier from this file again, by calling this function with the path to the file. Optionally specify the node for the file containing the classifier

Parameters

filepath	path to serialized NormalBayesClassifier
nodeName	name of node containing the classifier

virtual float cv::ml::NormalBayesClassifier::predictProb ( InputArray  inputs, OutputArray  outputs, OutputArray  outputProbs, int  flags = 0  ) const

pure virtual

Python:
	retval, outputs, outputProbs	=	cv.ml_NormalBayesClassifier.predictProb(	inputs[, outputs[, outputProbs[, flags]]]	)

Predicts the response for sample(s).

The method estimates the most probable classes for input vectors. Input vectors (one or more) are stored as rows of the matrix inputs. In case of multiple input vectors, there should be one output vector outputs. The predicted class for a single input vector is returned by the method. The vector outputProbs contains the output probabilities corresponding to each element of result.
