描述

read_class_knnread_class_knnReadClassKnnReadClassKnnReadClassKnnread_class_knn reads the saved classifier from the file FileNameFileNameFileNameFileNamefileNamefile_name (see write_class_knnwrite_class_knnWriteClassKnnWriteClassKnnWriteClassKnnwrite_class_knn). The values of the current classifier are overwritten. The default HALCON file extension for the k-NN classifier is 'gnc'.

运行信息

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.

参数表

FileNameFileNameFileNameFileNamefileNamefile_name (input_control)  filename.read → HTuplestrHTupleHtuple (string) (string) (HString) (char*)

File name of the classifier.

File extension: .gnc

结果

read_class_knnread_class_knnReadClassKnnReadClassKnnReadClassKnnread_class_knn returns 2 ( H_MSG_TRUE) . An exception is raised if it was not possible to open the file FileNameFileNameFileNameFileNamefileNamefile_name or the file has the wrong format.
