get_sample_class_gmm — Return a training sample from the training data of a Gaussian
Mixture Models (GMM).
get_sample_class_gmm reads out a training sample from the
Gaussian Mixture Model (GMM) given by
GMMHandle that was
add_samples_image_class_gmm. The index of the sample is
NumSample. The index is counted from 0,
NumSample must be a number between 0 and
NumSamples - 1, where
NumSamples can be
get_sample_num_class_gmm. The training
sample is returned in
Features is a feature vector of length
ClassID is its class (see
get_sample_class_gmm can, for example, be used to reclassify
the training data with
classify_class_gmm in order to
determine which training samples, if any, are classified
Index of the stored training sample.
Feature vector of the training sample.
Class of the training sample.

If the parameters are valid, the operator
get_sample_class_gmm returns the value 2 (H_MSG_TRUE). If necessary
an exception is raised.
