以下是几种常见的 Matlab 人脸检测算法的代码示例:
1. Viola-Jones 算法:
```matlab
% 加载分类器模型
faceDetector = vision.CascadeObjectDetector();
% 读取图像
img = imread('test.jpg');
% 检测人脸
bbox = step(faceDetector, img);
% 在图像上绘制矩形框
imgOut = insertShape(img, 'Rectangle', bbox);
% 显示结果
imshow(imgOut);
```
2. 基于 Haar 特征的人脸检测:
```matlab
% 加载分类器模型
faceDetector = vision.CascadeObjectDetector('ClassificationModel', 'haarcascade_frontalface_alt.xml');
% 读取图像
img = imread('test.jpg');
% 检测人脸
bbox = step(faceDetector, img);
% 在图像上绘制矩形框
imgOut = insertShape(img, 'Rectangle', bbox);
% 显示结果
imshow(imgOut);
```
3. 基于 LBP 特征的人脸检测:
```matlab
% 加载分类器模型
faceDetector = vision.CascadeObjectDetector('ClassificationModel', 'lbpcascade_frontalface.xml');
% 读取图像
img = imread('test.jpg');
% 检测人脸
bbox = step(faceDetector, img);
% 在图像上绘制矩形框
imgOut = insertShape(img, 'Rectangle', bbox);
% 显示结果
imshow(imgOut);
```
