Name
get_dl_classifier_resultT_get_dl_classifier_resultGetDlClassifierResultGetDlClassifierResultget_dl_classifier_result — Retrieve classification results inferred by a deep-learning-based
classifier.
Warning

Signature
def get_dl_classifier_result(dlclassifier_result_handle: HHandle, index: Union[int, str], gen_result_name: MaybeSequence[str]) -> Sequence[Union[str, float, int]]
def get_dl_classifier_result_s(dlclassifier_result_handle: HHandle, index: Union[int, str], gen_result_name: MaybeSequence[str]) -> Union[str, float, int]
Description
get_dl_classifier_resultget_dl_classifier_resultGetDlClassifierResultGetDlClassifierResultget_dl_classifier_result allows the user to return
classification results. These results are stored in the handle
DLClassifierResultHandleDLClassifierResultHandleDLClassifierResultHandleDLClassifierResultHandledlclassifier_result_handle and have been obtained from
the operator apply_dl_classifierapply_dl_classifierApplyDlClassifierApplyDlClassifierapply_dl_classifier.
The input parameter GenResultNameGenResultNameGenResultNamegenResultNamegen_result_name names the sort of result asked
and IndexIndexIndexindexindex identifies for which image the result is to be returned.
The respective value is given in GenResultValueGenResultValueGenResultValuegenResultValuegen_result_value.
Concretely, GenResultNameGenResultNameGenResultNamegenResultNamegen_result_name can attain the following values:
- 'confidences'"confidences""confidences""confidences""confidences":
-
return the confidences values for the
selected image IndexIndexIndexindexindex.
- 'predicted_classes'"predicted_classes""predicted_classes""predicted_classes""predicted_classes":
-
return the names of the inferred
classes for the selected image IndexIndexIndexindexindex.
- 'predicted_class_indices'"predicted_class_indices""predicted_class_indices""predicted_class_indices""predicted_class_indices":
return the indices of
the inferred classes for the selected image IndexIndexIndexindexindex.
The class indices correspond to the positions within the array of
classes (counting from 0).
The input parameter IndexIndexIndexindexindex can attain the value 'all'"all""all""all""all", in
which case get_dl_classifier_resultget_dl_classifier_resultGetDlClassifierResultGetDlClassifierResultget_dl_classifier_result returns the confidence value,
respectively class, for the best candidate (prediction with the
highest confidence value) for each image of the input batch.
Otherwise, IndexIndexIndexindexindex must be an integer selecting one of the input
images in the batch, in which case get_dl_classifier_resultget_dl_classifier_resultGetDlClassifierResultGetDlClassifierResultget_dl_classifier_result returns
all output classes, respectively, confidences sorted by decreasing
confidence value. This is useful in order to retrieve the best K candidates
for a given input. As we start indexing at 0, IndexIndexIndexindexindex must
have a value between 0 and the size of the batch of input images
minus one.
For an explanation of the concept of deep-learning-based classification
see the introduction of chapter Deep Learning / Classification.
The workflow involving this legacy operator is described in the chapter
Legacy / DL Classification.

Result
If the parameters are valid, the operator
get_dl_classifier_resultget_dl_classifier_resultGetDlClassifierResultGetDlClassifierResultget_dl_classifier_result returns the value 2 (
H_MSG_TRUE)
. If
necessary, an exception is raised.
