In this project, we develop a face recognize platform based on MTCNN object-detection netcwork and FaceNet self-supervised network.

Overview

模式识别大作业——人脸检测与识别平台

本项目是一个简易的人脸检测识别平台,提供了人脸信息录入人脸识别的功能。前端采用 html+css+js,后端采用 pytorch,前后端交互采用 flask。

MTCNN_FaceNet:人脸检测算法接口

simplified:人脸识别算法接口

static:静态资源文件夹(包含数据库)

templates:前端Html框架

app.py:前后端交互flask框架

2 人脸识别算法——facenet

  • 一次性导入数据库:使用 face_in.py,请将数据库中每个人组织成单个文件夹的形式,如图

    image-20211121230548707

    • 格式为 python face_in.py -i -d
    • 样例输入:python face_in.py -i In_data -d dataset.json
    • 样例输出:在当前工作目录下生成(default)名为"dataset.json"的文件,即为数据库
    • 若为直接调用函数的话,传入包含上面两种信息的字典即可,输出不变
      • 即类似 {'image_path':<>, 'dataset_path':<>} 的参数
  • 添加单个人像:使用 face_append.py,格式为 python face_append.py -i -n -d

    • 样例输入:python face_append.py -i In_data/acatsa/acatsa.1.jpg -n acatsa -d dataset.json
    • 样例输出:修改指定的 dataset.json,向其中添加新的人脸数据
    • 若为直接调用函数的话,传入包含上面三种信息的字典即可,输出不变
      • 即类似 {'image_path':<>, 'dataset_path':<>, 'name':<>} 的参数
  • 从数据库中判别人脸:使用 classify_func.py,格式为 python classify_func.py -i -d

    • 样例输入: python classify_func.py -i In_data/acatsa/acatsa.1.jpg -d dataset.json
    • 样例输出:'acatsa'
    • 若为直接调用函数的话,传入包含上面三种信息的字典即可,输出不变
      • 即类似 {'image_path':<>, 'dataset_path':<>} 的参数
  • 剪切人脸 和 输出特征向量的 接口,见 interface.py 中的 mtcnn_single() 和 embedding_single() 函数

    • mtcnn_single()
      • 输入:字典,{'image_path':<>, 'save_path':< default:None >}
      • 输出:返回剪切后的图片,同时在 save_path 保存剪切后的图片
    • embedding_single()
      • 输入:字典, {'image_path':<>}
      • 输出:返回编码向量
  • 一键将图片库中人脸进行 mtcnn 剪裁,见 mtcnn_trans() 函数

    • 输入:字典,{'image_path':<>}

    • 输出:无返回值,剪裁后替换原有图片位置

    • 注意:需要图片库的组织形式如本文开头 face_in.py 的要求那样见 mtcnn_trans() 函数

  • classify_test() 函数

    • 输入:字典,{'img_path':<>, 'dataset_path':<>, 'origin_data':<>}
      • img_path,输入图片的路径位置
      • dataset_path,之前保存的数据 json
      • origin_data,图片的保存位置,即各个人脸的总保存位置
      • image-20211225172640828
      • 就像上面这样的话,origin_data = 'In_data'
    • 输出:
      • 若找到匹配的人脸。返回路径,示例:'In_data/acatsa/acatsa_1.jpg'
      • 若未找到,返回字符串 'no matched people'

3 人脸检测算法——mtcnn

4 平台使用

本平台采用flask框架搭建,运行时,在flask_FC文件夹下打开终端,运行如下指令:

python -m flask run

在浏览器中输入网址 http://127.0.0.1:5000/

前端设置了两个接口,分别进行信息录入人脸截图识别。将新录入的人脸图片传入后端,可利用mtcnn算法进行人脸检测,在数据库中加入该用户的人脸信息;将视频流截图后的图片传入后端,可利用facenet算法进行人脸识别,在后台数据库中信息匹配,返回识别成功或错误信息。

4.1 人脸信息录入

form表单将文件流传入后端 —— mtcnn接口检测人脸 —— DataBase中更新图片信息 —— dataset.json中更新编码信息 —— 检测人脸图片返回前端

aaa.html

">
<form action="/" id="uploadForm" method="post" enctype="multipart/form-data" >
	<button class="btn btn-danger" type="submit" >
      <h3>Enter Photo to experienceh3> 
    button>
	<input type="file" name="photo">
form>

app.py

@app.route('/', methods=['GET', 'POST'])
def upinfo():
    if request.method == 'POST':
        if request.files.get('photo'):
            # 创建文件夹,保存录入图片
            photo = request.files.get('photo')
            basepath = os.path.dirname(__file__)
            filename = secure_filename(photo.filename)
            uploadpath = os.path.join(basepath, 'static/DataBase', filename[:-4], filename)
            path = os.path.join(basepath, 'static/DataBase', filename[:-4])
            if not path:
                os.makedirs(path)

            Reshape = transforms.Resize((160, 160))
            trans = transforms.Compose([Reshape])
            img = trans(tojpg(Image.open(photo)))
            save_path = uploadpath
            newphoto = mtcnn_single(img, save_path=save_path)

            # 更新dataset.json
            args = {'image_path': uploadpath, "dataset_path": 'static/face_dataset.json', 'name': filename[:-4]}
            face_append(args)
            return render_template('aaa.html', output='DataBase/' + filename[:-4] + '/' + filename)

    return render_template('aaa.html')

4.2 视频流截图检测

前端视频流截图传入后端 —— facenet接口识别人脸 —— 后端数据库匹配 —— 返回数据库已录入图片(匹配成功)/返回失败信息

aaa.html

">

			<script>

				let v = document.getElementById("myVideo");

				//create a canvas to grab an image for upload
				let imageCanvas = document.createElement('canvas');
				let imageCtx = imageCanvas.getContext("2d");

				//Add file blob to a form and post
				function postFile(file) {
					let formdata = new FormData();
					formdata.append("image", file);
					let xhr = new XMLHttpRequest();
					xhr.open('POST', 'http://localhost:5000/', true);
					xhr.onload = function () {
						if (this.status === 200){
							var path = JSON.parse(this.response)['path']
							console.log(this.response['path']);
							$('#img').attr('src',path);
						}
						else
							console.error(xhr);
					};
					xhr.send(formdata);
				}

				//Get the image from the canvas
				function sendImagefromCanvas() {

					//Make sure the canvas is set to the current video size
					imageCanvas.width = v.videoWidth;
					imageCanvas.height = v.videoHeight;

					imageCtx.drawImage(v, 0, 0, v.videoWidth, v.videoHeight);

					//Convert the canvas to blob and post the file
					imageCanvas.toBlob(postFile, 'image/jpeg');
				}

				//Take a picture on click
				v.onclick = function() {
					console.log('click');
					sendImagefromCanvas();
				};

				window.onload = function () {

					//Get camera video
					navigator.mediaDevices.getUserMedia({video: {width: 640, height: 360}, audio: false})
						.then(stream => {
							v.srcObject = stream;
						})
						.catch(err => {
							console.log('navigator.getUserMedia error: ', err)
						});

				};
