load_detection_model(model_name: str) -> BaseDetectionModel

Instantiate the model implementation registered under model_name.

PARAMETER	DESCRIPTION
model_name	Registered model name, or "None" to select the dummy model. TYPE: str

RETURNS	DESCRIPTION
BaseDetectionModel	Model implementation for the requested TorchVision, YOLO, MTCNN, or dummy model.

Note

TorchVision, YOLO, and MTCNN names select their matching backend wrapper.

RAISES	DESCRIPTION
DetectionModelError	If the name is not registered by any supported backend.
