描述

clear_samples_class_gmmclear_samples_class_gmmClearSamplesClassGmmClearSamplesClassGmmClearSamplesClassGmmclear_samples_class_gmm clears all training samples that have been stored in the Gaussian Mixture Model (GMM) GMMHandleGMMHandleGMMHandleGMMHandleGMMHandlegmmhandle. clear_samples_class_gmmclear_samples_class_gmmClearSamplesClassGmmClearSamplesClassGmmClearSamplesClassGmmclear_samples_class_gmm should only be used if the GMM is trained in the same process that uses the GMM for evaluation with evaluate_class_gmmevaluate_class_gmmEvaluateClassGmmEvaluateClassGmmEvaluateClassGmmevaluate_class_gmm or for classification with classify_class_gmmclassify_class_gmmClassifyClassGmmClassifyClassGmmClassifyClassGmmclassify_class_gmm。In this case, the memory required for the training samples can be freed with clear_samples_class_gmmclear_samples_class_gmmClearSamplesClassGmmClearSamplesClassGmmClearSamplesClassGmmclear_samples_class_gmm, and hence memory can be saved. In the normal usage, in which the GMM is trained offline and written to a file with write_class_gmmwrite_class_gmmWriteClassGmmWriteClassGmmWriteClassGmmwrite_class_gmm, it is typically unnecessary to call clear_samples_class_gmmclear_samples_class_gmmClearSamplesClassGmmClearSamplesClassGmmClearSamplesClassGmmclear_samples_class_gmm because write_class_gmmwrite_class_gmmWriteClassGmmWriteClassGmmWriteClassGmmwrite_class_gmm does not save the training samples, and hence the online process, which reads the GMM with read_class_gmmread_class_gmmReadClassGmmReadClassGmmReadClassGmmread_class_gmm, requires no memory for the training samples.

执行信息

• 多线程类型：可重入（与非独占算子并行运行）。
• 多线程作用域：全局（可从任何线程调用）。
• 未采用并行化处理。

此算子修改后续输入参数的状态：

• GMMHandleGMMHandleGMMHandleGMMHandleGMMHandlegmmhandle

在执行此算子时，若该参数值需在多个线程间使用，则必须对其访问进行同步。

参数

结果

如果参数有效，算子 clear_samples_class_gmmclear_samples_class_gmmClearSamplesClassGmmClearSamplesClassGmmClearSamplesClassGmmclear_samples_class_gmm 返回值 2 ( H_MSG_TRUE )。如有必要，则抛出异常。
