# Arcaea Offline OCR
## Example
```py
import cv2
from arcaea_offline_ocr.device.ocr import DeviceOcr
from arcaea_offline_ocr.device.rois.definition import DeviceRoisAutoT2
from arcaea_offline_ocr.device.rois.extractor import DeviceRoisExtractor
from arcaea_offline_ocr.device.rois.masker import DeviceRoisMaskerAutoT2
from arcaea_offline_ocr.phash_db import ImagePhashDatabase
img_path = "/path/to/opencv/supported/image/formats.jpg"
img = cv2.imread(img_path, cv2.IMREAD_COLOR)
rois = DeviceRoisAutoT2(img.shape[1], img.shape[0])
extractor = DeviceRoisExtractor(img, rois)
masker = DeviceRoisMaskerAutoT2()
knn_model = cv2.ml.KNearest.load("/path/to/trained/knn/model.dat")
phash_db = ImagePhashDatabase("/path/to/image/phash/database.db")
ocr = DeviceOcr(extractor, masker, knn_model, phash_db)
print(ocr.ocr())
```
```sh
$ python example.py
DeviceOcrResult(rating_class=2, pure=1135, far=11, lost=0, score=9953016, max_recall=1146, song_id='ringedgenesis', song_id_possibility=0.953125, clear_status=2, partner_id='45', partner_id_possibility=0.8046875)
