描述

read_class_svmread_class_svmReadClassSvmReadClassSvmReadClassSvmread_class_svm reads a support vector machine (SVM) that has been stored with write_class_svmwrite_class_svmWriteClassSvmWriteClassSvmWriteClassSvmwrite_class_svm。Since the training of an SVM can consume a relatively long time, the SVM is typically trained in an offline process and written to a file with write_class_svmwrite_class_svmWriteClassSvmWriteClassSvmWriteClassSvmwrite_class_svm。In the online process the SVM is read with read_class_svmread_class_svmReadClassSvmReadClassSvmReadClassSvmread_class_svm and subsequently used for classification with classify_class_svmclassify_class_svmClassifyClassSvmClassifyClassSvmClassifyClassSvmclassify_class_svm。The default HALCON file extension for the SVM classifier is 'gsc'.

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。

此算子返回一个句柄。请注意，即使该句柄被用作特定算子的输入参数，这些算子仍可能改变此句柄类型的实例状态。
