Python在智能监控系统中的关键作用

import cv2

# 加载训练好的人脸识别模型
face_cascade = cv2.CascadeClassifier('haarcascade_frontalface_default.xml')

# 加载图像
image = cv2.imread('test.jpg')

# 转换为灰度图像
gray = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)

# 检测人脸
faces = face_cascade.detectMultiScale(gray, scaleFactor=1.1, minNeighbors=5)

# 在图像上标记人脸
for (x, y, w, h) in faces:
    cv2.rectangle(image, (x, y), (x + w, y + h), (0, 255, 0), 2)

# 显示结果
cv2.imshow('Face Detection', image)
cv2.waitKey(0)
cv2.destroyAllWindows()

import pandas as pd
from sklearn.ensemble import IsolationForest

# 加载数据
data = pd.read_csv('data.csv')

# 筛选所需的特征
features = ['temperature', 'humidity', 'pressure']
X = data[features]

# 使用孤立森林算法进行异常检测
clf = IsolationForest(contamination=0.1)
clf.fit(X)

# 预测异常样本
predictions = clf.predict(X)

# 输出异常样本
anomalies = data[predictions == -1]
print(anomalies)
