Opencv比较两个人脸嵌入

Question

我经历了Pyimagesearch face Recognition tutorial, 但我的应用程序只需要比较两张脸，我嵌入了两张脸，如何使用 opencv 比较它们？ link中提到了关于用于从面部提取嵌入的训练模型，我想知道我应该尝试用什么方法来比较两个人脸嵌入。

（注：我是新手）

Answer 1

首先，您的案例与给定的教程相似，您需要将单张图像与测试图像进行比较，而不是多张图像，

所以你真的不需要训练步骤。

你可以做到

# read 1st image and store encodings
image = cv2.imread(args["image"])
rgb = cv2.cvtColor(image, cv2.COLOR_BGR2RGB)

boxes = face_recognition.face_locations(rgb, model=args["detection_method"])
encodings1 = face_recognition.face_encodings(rgb, boxes)

# read 2nd image and store encodings
image = cv2.imread(args["image"])
rgb = cv2.cvtColor(image, cv2.COLOR_BGR2RGB)

boxes = face_recognition.face_locations(rgb, model=args["detection_method"])
encodings2 = face_recognition.face_encodings(rgb, boxes)


# now you can compare two encodings
# optionally you can pass threshold, by default it is 0.6
matches = face_recognition.compare_faces(encoding1, encoding2)

matches 会根据你的图片给你 True 或 False

Answer 2

根据您提到的文章，您实际上可以仅使用 face_recognition library.

来比较两张脸是否相同

可以使用compare faces判断两张图片是否是同一张脸

import face_recognition
known_image = face_recognition.load_image_file("biden.jpg")
unknown_image = face_recognition.load_image_file("unknown.jpg")

biden_encoding = face_recognition.face_encodings(known_image)[0]
unknown_encoding = face_recognition.face_encodings(unknown_image)[0]

results = face_recognition.compare_faces([biden_encoding], unknown_encoding)

Opencv比较两个人脸嵌入

Open cv compare two face embeddings
