描述
write_samples_class_svmwrite_samples_class_svmWriteSamplesClassSvmWriteSamplesClassSvmWriteSamplesClassSvmwrite_samples_class_svm writes the training samples
currently stored in the support vector machine (SVM)
SVMHandleSVMHandleSVMHandleSVMHandleSVMHandlesvmhandle to the file given by FileNameFileNameFileNameFileNamefileNamefile_name.
write_samples_class_svmwrite_samples_class_svmWriteSamplesClassSvmWriteSamplesClassSvmWriteSamplesClassSvmwrite_samples_class_svm can be used to build up a database
of training samples, and hence to improve the performance of the SVM
by training it with an extended data set (see
train_class_svmtrain_class_svmTrainClassSvmTrainClassSvmTrainClassSvmtrain_class_svm). The file FileNameFileNameFileNameFileNamefileNamefile_name is overwritten
by write_samples_class_svmwrite_samples_class_svmWriteSamplesClassSvmWriteSamplesClassSvmWriteSamplesClassSvmwrite_samples_class_svm. Nevertheless, extending the
database of training samples is easy to do because
read_samples_class_svmread_samples_class_svmReadSamplesClassSvmReadSamplesClassSvmReadSamplesClassSvmread_samples_class_svm and add_sample_class_svmadd_sample_class_svmAddSampleClassSvmAddSampleClassSvmAddSampleClassSvmadd_sample_class_svm add
the training samples to the training samples that are already stored
in memory with the SVM.
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。
参数
