-The models and dependencies should download automatically. To install them manually, follow the [official instructions for installing mmdet](https://mmcv.readthedocs.io/en/latest/get_started/installation.html#install-with-mim-recommended). The models can be [downloaded here](https://huggingface.co/dustysys/ddetailer) and should be placed in `/models/mmdet/bbox` for bounding box (`anime-face_yolov3`) or `/models/mmdet/segm` for instance segmentation models (`dd-person_mask2former`). See the [MMDetection docs](https://mmdetection.readthedocs.io/en/latest/1_exist_data_model.html) for guidance on training your own models.

 ## Usage
 Select Detection Detailer as the script in SD web UI to use the extension. Here are some tips:
 - `anime-face_yolov3` can detect the bounding box of faces as the primary model while `dd-person_mask2former` isolates the head's silhouette as the secondary model by using the bitwise AND option.
 - The dilation factor expands the mask, while the x & y offsets move the mask around.
 - The script is available in txt2img mode as well and can improve the quality of your 10 pulls with moderate settings (low denoise).
