Detections Classes Replacement

Class: DetectionsClassesReplacementBlockV1

Source: inference.core.workflows.core_steps.fusion.detections_classes_replacement.v1.DetectionsClassesReplacementBlockV1

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

Input and Output Bindings

The available connections depend on its binding kinds. Check what binding kinds Detections Classes Replacement in version v1 has.

Bindings

• input

  • object_detection_predictions (Union[object_detection_prediction, instance_segmentation_prediction, keypoint_detection_prediction]): The output of a detection model describing the bounding boxes that will have classes replaced..
  • classification_predictions (classification_prediction): The output of classification model for crops taken based on RoIs pointed as the other parameter.

• output

  • predictions (Union[object_detection_prediction, instance_segmentation_prediction, keypoint_detection_prediction]): Prediction with detected bounding boxes in form of sv.Detections(...) object if object_detection_prediction or Prediction with detected bounding boxes and segmentation masks in form of sv.Detections(...) object if instance_segmentation_prediction or Prediction with detected bounding boxes and detected keypoints in form of sv.Detections(...) object if keypoint_detection_prediction.
