Args: key_points: RF-DETR keypoint prediction output. image: Optional image identifier added to each output row. Paths are represented by their file name. keypoint_threshold: Per-keypoint confidence threshold used when ``key_points.visible`` is not already populated. Returns: A list of row dictionaries, one per visible/non-zero keypoint.
