訓練人臉識別模型

Question

我正在用 Python 編寫人臉識別器，但在訓練部分遇到了麻煩。

這是我的代碼：

import cv2
import numpy as np
from os import listdir
from os.path import isfile, join
data_path = 'E:/Documents/7thSemester/Project/OpenCV-master/faces'
onlyfiles = [f for f in listdir(data_path) if isfile(join(data_path,f))]
Training_Data, Labels = [], []

for i, files in enumerate(onlyfiles):
    image_path = data_path + onlyfiles[i]
    images = cv2.imread(image_path, cv2.IMREAD_GRAYSCALE)
    Training_Data.append(np.asarray(images, dtype=np.uint8))
    Labels.append(i)

Labels = np.asarray(Labels, dtype=np.int32)
model = cv2.face.LBPHFaceRecognizer_create()
model.train(np.asarray(Training_Data), np.asarray(Labels))
print("Model Training Complete!!!!!")

我收到以下錯誤：

Traceback (most recent call last):
  File "facial_recognition_part2.py", line 19, in <module>
    model = cv2.face.LBPHFaceRecognizer_create()
AttributeError: module 'cv2.cv2' has no attribute 'face'

Answer 1

請將 opencv-contrib 安裝為：

pip install opencv-contrib

或者

pip install opencv_contrib_python

Answer 2

看看這行代碼是否適用於我的程序：

cv2.face.createLBPHFaceRecognizer()

如果它仍然不起作用，您應該考慮重新安裝 OpenCV

pip uninstall opencv-contrib-python
pip install opencv-contrib-python
