如何使用DeepFace.detectFace实际检测图像中的人脸？

问题描述

我正在尝试识别和计算包含图片的文件夹的每张图片中人脸的数量，我正在使用Deepface完成这项工作。我在网络上仅找到一个对函数DeepFace.detectFace()的引用，据说可以识别人脸，但是我在实现该框架时遇到了一些问题，除此功能之外，我没有找到该功能的任何其他引用：Face Alignment for Face Recognition in Python within OpenCV

输入文件仅是“ jpg”和“ jpeg”文件。

我的代码如下：

from deepface import DeepFace
import os
import os.path
import numpy as np

BASE_DIR = os.path.dirname(os.path.abspath(__file__))
imgs = []
path = os.path.join(BASE_DIR,'images')
valid_images = [".jpg",".gif",".png",".tga",".jpeg"]
# image = Image.open(os.path.join(path,file))

for file in os.listdir(path):
    print(file)
    ext = os.path.splitext(file)[1]
    if ext.lower() not in valid_images:
        continue
    print(ext)
    image_face = DeepFace.detectFace(file)
    print(image_face)

然后出现以下错误：

解决方法

您要输入文件名。您应该提供图像数组。

$ awk '{sub("AAAAAA","x"(++x)); y=0; while(sub("BBBBBB","y"(++y)));}1' file

x1 this is some content.
This is x2 some more content y1. y2 y3
This is yet x3 some more y1 y2 y3 content.

输出：

,

将确切的图像路径传递给detectFace函数效果很好，而不是通过opencv读取它。

#!pip install deepface
from deepface import DeepFace
img = DeepFace.detectFace("img1.jpg")
