# Simple but powerful face detection
face_cascade = cv2.CascadeClassifier(cv2.data.haarcascades + 'haarcascade_frontalface_default.xml')
img = cv2.imread('group_photo.jpg')
gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
faces = face_cascade.detectMultiScale(gray, 1.1, 4)

for (x, y, w, h) in faces:
    cv2.rectangle(img, (x, y), (x+w, y+h), (255, 0, 0), 2)
        

What makes it indispensable:

• Massive function library for any vision task imaginable
• Hardware acceleration for real-time processing
• Seamless integration with machine learning frameworks

I built a motion detection system for a small business that cost less than $200 in hardware but performs better than commercial systems costing thousands. The learning curve is steep, but the power it unlocks is worth every minute of study.

    # Log parameters
    mlflow.log_param("learning_rate", 0.01)
    mlflow.log_param("epochs", 100)
    
    # Train model
    model = train_model(learning_rate=0.01, epochs=100)
    
    # Log metrics
    mlflow.log_metric("accuracy", 0.92)
    
    # Save the model
    mlflow.sklearn.log_model(model, "model")
