read_class_gmm — Read a Gaussian Mixture Model from a file.
read_class_gmm reads a Gaussian Mixture Model (GMM) that has been stored with write_class_gmm. Since the training of an GMM can consume a relatively long time, the GMM is typically trained in an offline process and written to a file with write_class_gmm. In the online process the GMM is read with read_class_gmm and subsequently used for evaluation with evaluate_class_gmm or for classification with classify_class_gmm. The default HALCON file extension for the GMM classifier is 'ggc'.
This operator returns a handle. Note that the state of an instance of this handle type may be changed by specific operators even though the handle is used as an input parameter by those operators.
File extension: .ggc
If the parameters are valid, the operator read_class_gmm returns the value 2 (H_MSG_TRUE). If necessary an exception is raised.
