"""
Detect human censor points in anime images.
This function uses pre-trained YOLOv8 models to identify and locate specific
anatomical features that are typically censored in anime images. It can detect
female nipples, male genitals, and female genitals.
:param image: The input image to be analyzed. Can be a file path, URL, or image data.
:type image: ImageTyping
:param level: The model level to use, either 's' (standard) or 'n' (nano).
The 'n' model is faster but less accurate, while 's' is more accurate but slower.
:type level: str
:param version: The version of the model to use. Default is 'v1.0'.
:type version: str
:param model_name: Optional custom model name. If not provided, it will be constructed
from the version and level.
:type model_name: Optional[str]
:param conf_threshold: The confidence threshold for detections. Only detections with
confidence above this value will be returned. Default is 0.3.
:type conf_threshold: float
:param iou_threshold: The Intersection over Union (IoU) threshold for non-maximum
suppression. Detections with IoU above this value will be merged.
Default is 0.7.
:type iou_threshold: float
:return: A list of tuples, each containing:
- A tuple of four integers (x0, y0, x1, y1) representing the bounding box
- A string indicating the type of detection ('nipple_f', 'penis', or 'pussy')
- A float representing the confidence score of the detection
:rtype: List[Tuple[Tuple[int, int, int, int], str, float]]
:raises ValueError: If an invalid level is provided.
:raises RuntimeError: If the model fails to load or process the image.
