注冊 face_recognition

Question

我正在嘗試使用 python 為我的 face_recognition 應用程序做一個基本的注冊

#Here I'm trying to register faces more easier than need to add every face editing my script 

我需要一些方法來添加人員，注冊然后可以識別任何幫助表示贊賞，謝謝

這就是我所有的代碼測試，我正在嘗試做我的朋友對我說的話，但我是 Python 新手，所以我需要更多幫助。

這是一個face_recognition 代碼，我正在學習python 為aprimorate 此代碼以幫助我在大學！ 所以我非常適合你的幫助

import face_recognition

image_of_henrique = face_recognition.load_image_file("./img/known/Henrique_.PNG")

Answer 1

按照您的代碼，您可以執行以下操作：

class KnowledgeBase:

    def __init__(self):
        self.names = []
        self.faces = []


    def register_face(self, name, img_path):
        image = face_recognition.load_image_file(img_path) 
        encoded_face = face_recognition.face_encodings(image)[0]
        self.names.append(name)
        self.faces.append(encoded_face)

然后您只需要實例化一個 KnowledgeBase 元素並向其添加新數據。 如果需要，這可以在一個單獨的文件中：

kb = KnowledgeBase()
kb.register_face('Patricia', './img/known/Patricia.jpg')
kb.register_face('Victor', './img/known/Victor.jpg')
kb.register_face('Henrique', './img/known/Henrique_.PNG')
