Detections Classes Replacement¶
Version v1¶
Combine results of detection model with classification results performed separately for each and every bounding box.
Bounding boxes without top class predicted by classification model are discarded, for multi-label classification results, most confident label is taken as bounding box class.
Type identifier¶
Use the following identifier in step "type" field: roboflow_core/detections_classes_replacement@v1to add the block as
as step in your workflow.
Properties¶
| Name | Type | Description | Refs |

The Refs column marks possibility to parametrise the property with dynamic values available
in workflow runtime. See Bindings for more info.
