Description

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

Parameters

FileNameFileNameFileNameFileNameFileNamefileName (input_control)  filename.read → HTupleHTupleHTupleVARIANTHtuple (string) (string) (HString) (char*) (BSTR) (char*)

File name of the classifier.

File extension: .gnc

Handle of the k-NN classifier.

Result

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