python - face_recognition 编码从字符串回到 python 中的原始编码

Question

我正在探索 python 中的 face_recognition https://github.com/ageitgey/face_recognition

目前，我将 face_encoding 存储在一个字符串中。您可以看到我如何转换为字符串数组，以便将其保存在数据库中。

unknown_image = face_recognition.load_image_file("biden.jpg")
face_location_unknown = face_recognition.face_locations(unknown_image)
unknown_encoding = face_recognition.face_encodings(unknown_image, face_location_unknown)[0]


#conversion to string
unknown_encoding_string = "%s" % unknown_encoding
face_unknown_encoding_string = re.sub('\s+', ', ', unknown_encoding_string[1:-1])

“face_unknown_encoding_string”是这样的:

问题是我如何转换它

face_unknown_encoding_string 

回到与“unknown_encoding”相同的编码格式？

原因是我现在想使用“compare_faces”进行比较

Answer 1

上帝，那个评论者没用。

我有一个非常相似的问题，我需要将一堆序列化的面部编码与一个新的面部编码进行比较，看看它是否是同一个人，因此解决了:

face_recognition.compare_faces(np.array(json.loads(person.face_encodings)), np.array(json.loads(unrecognized_rectangle.face_encoding)))
