Method Detail

clear

public void clear()

predict

public float predict(Mat samples)

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 samples. In case of multiple input vectors, there should be one output vector results. The predicted class for a single input vector is returned by the method.

The function is parallelized with the TBB library.

Parameters:

samples - a samples

predict

public float predict(Mat samples,
                     Mat results)

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 samples. In case of multiple input vectors, there should be one output vector results. The predicted class for a single input vector is returned by the method.

The function is parallelized with the TBB library.

Parameters:

samples - a samples

results - a results

train

public boolean train(Mat trainData,
                     Mat responses)

Trains the model.

The method trains the Normal Bayes classifier. It follows the conventions of the generic "CvStatModel.train" approach with the following limitations:

• Only CV_ROW_SAMPLE data layout is supported.
• Input variables are all ordered.
• Output variable is categorical, which means that elements of responses must be integer numbers, though the vector may have the CV_32FC1 type.
• Missing measurements are not supported.

Parameters:

trainData - a trainData

responses - a responses

See Also:

org.opencv.ml.CvNormalBayesClassifier.train

train

public boolean train(Mat trainData,
                     Mat responses,
                     Mat varIdx,
                     Mat sampleIdx,
                     boolean update)

• Missing measurements are not supported.

Parameters:

trainData - a trainData

responses - a responses

varIdx - a varIdx

sampleIdx - a sampleIdx

update - Identifies whether the model should be trained from scratch (update=false) or should be updated using the new training data (update=true).
