test_sampset_boxT_test_sampset_boxTestSampsetBoxTestSampsetBoxtest_sampset_box (Operator)

test_sampset_boxT_test_sampset_boxTestSampsetBoxTestSampsetBoxtest_sampset_box — Classify a set of arrays.

Warning

test_sampset_boxtest_sampset_boxTestSampsetBoxTestSampsetBoxtest_sampset_box is obsolete and is only provided for reasons of backward compatibility. New applications should use the MLP, SVM, KNN or GMM operators instead. The operator will be removed with HALCON 25.11.

Herror T_test_sampset_box(const Htuple ClassifHandle, const Htuple SampKey, Htuple* Error)

Description

In contrast to learn_sampset_boxlearn_sampset_boxLearnSampsetBoxLearnSampsetBoxlearn_sampset_box there is not a learning here. Typically you use test_sampset_boxtest_sampset_boxTestSampsetBoxTestSampsetBoxtest_sampset_box to classify independent test data. ErrorErrorErrorerrorerror gives you information about the applicability of the learned training set on new examples.

Execution Information

• Multithreading type: reentrant (runs in parallel with non-exclusive operators).
• Multithreading scope: global (may be called from any thread).
• Processed without parallelization.

Parameters

ClassifHandleClassifHandleClassifHandleclassifHandleclassif_handle (input_control)  class_box → HClassBox, HTupleHHandleHTupleHtuple (handle) (IntPtr) (HHandle) (handle)

Handle of the classifier.

SampKeySampKeySampKeysampKeysamp_key (input_control)  feature_set → HFeatureSet, HTupleHHandleHTupleHtuple (handle) (IntPtr) (HHandle) (handle)

Key of the test data.

Error during the assignment.

Result

test_sampset_boxtest_sampset_boxTestSampsetBoxTestSampsetBoxtest_sampset_box returns 2 ( H_MSG_TRUE) . An exception is raised, if if key SampKeySampKeySampKeysampKeysamp_key does not exist or problems occur while opening the file.
