Name
read_class_gmmT_read_class_gmmReadClassGmmReadClassGmmread_class_gmm — Read a Gaussian Mixture Model from a file.
Signature
def read_class_gmm(file_name: str) -> HHandle
Description
read_class_gmmread_class_gmmReadClassGmmReadClassGmmReadClassGmmread_class_gmm reads a Gaussian Mixture Model (GMM) that has
been stored with write_class_gmmwrite_class_gmmWriteClassGmmWriteClassGmmWriteClassGmmwrite_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_gmmwrite_class_gmmWriteClassGmmWriteClassGmmWriteClassGmmwrite_class_gmm. In the online process the GMM is read with
read_class_gmmread_class_gmmReadClassGmmReadClassGmmReadClassGmmread_class_gmm and subsequently used for evaluation with
evaluate_class_gmmevaluate_class_gmmEvaluateClassGmmEvaluateClassGmmEvaluateClassGmmevaluate_class_gmm or for classification with
classify_class_gmmclassify_class_gmmClassifyClassGmmClassifyClassGmmClassifyClassGmmclassify_class_gmm.
The default HALCON file extension for the GMM classifier is 'ggc'.
Execution Information
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
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.
Parameters

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