[英]Why is face_recognition module not working for me in Python?
我正在 Python 中制作人脸识别脚本。 我正在使用 Python 中的 face_recognition 模块。 但是当我运行代码时,我得到一个 output 说: -
Please install `face_recognition_models` with this command before using `face_recognition`:
pip install git+https://github.com/ageitgey/face_recognition_models
Process finished with exit code 0
我运行了它建议的命令,并且还安装了“face_recognition_models”。 但它仍然要求我安装模块。 你能帮忙吗?
这是我的代码:-
import numpy as np
import face_recognition as fr
import cv2
video_capture = cv2.VideoCapture(0)
my_image = fr.load_image_file("face.jpg")
my_face_encoding = fr.face_encodings(bruno_image)[0]
known_face_encondings = [my_face_encoding]
known_face_names = ["Adrian"]
while True:
ret, frame = video_capture.read()
rgb_frame = frame[:, :, ::-1]
face_locations = fr.face_locations(rgb_frame)
face_encodings = fr.face_encodings(rgb_frame, face_locations)
for (top, right, bottom, left), face_encoding in zip(face_locations, face_encodings):
matches = fr.compare_faces(known_face_encondings, face_encoding)
name = "Unknown"
face_distances = fr.face_distance(known_face_encondings, face_encoding)
best_match_index = np.argmin(face_distances)
if matches[best_match_index]:
name = known_face_names[best_match_index]
cv2.rectangle(frame, (left, top), (right, bottom), (0, 0, 255), 2)
cv2.rectangle(frame, (left, bottom - 35), (right, bottom), (0, 0, 255), cv2.FILLED)
font = cv2.FONT_HERSHEY_SIMPLEX
cv2.putText(frame, name, (left + 6, bottom - 6), font, 1.0, (255, 255, 255), 1)
cv2.imshow('Webcam_facerecognition', frame)
if cv2.waitKey(1) & 0xFF == ord('q'):
break
video_capture.release()
cv2.destroyAllWindows()
如果你想深入了解,那么这可以用几行代码来处理。 此外,它是基于 keras 的库。 这就是为什么它易于安装和运行。 另一方面,face_recognition 主要基于 dlib,安装运行困难。
在这里,您应该将扩展名为 .jpg 或 .png 的面部图像存储在 c:/facial_database 文件夹中。
#!pip install deepface
from deepface import DeepFace
DeepFace.stream(db_path = "C:/facial_database", model_name = 'Facenet')
