� Code Examples & Quick Start

🎯 Basic OpenCV Operations
import cv2
import numpy as np

def process_image(image_path):
    # Read image
    img = cv2.imread(image_path)
    
    # Basic processing pipeline
    gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
    blur = cv2.GaussianBlur(gray, (5,5), 0)
    edges = cv2.Canny(blur, 100, 200)
    
    # Display results
    cv2.imshow('Original', img)
    cv2.imshow('Processed', edges)
    cv2.waitKey(0)
    
    return edges

# Example usage
process_image('path/to/image.jpg')
🤖 Deep Learning with YOLO
from ultralytics import YOLO
import cv2
import numpy as np

def detect_objects(image_path):
    # Load model
    model = YOLO('yolov8n.pt')
    
    # Perform inference
    results = model(image_path)
    
    # Process results
    for r in results:
        boxes = r.boxes
        for box in boxes:
            # Get box coordinates
            x1, y1, x2, y2 = box.xyxy[0]
            # Get class name
            cls = int(box.cls[0])
            # Get confidence score
            conf = box.conf[0]
            print(f"Detected {model.names[cls]} with confidence {conf:.2f}")
    
    # Show results
    img = cv2.imread(image_path)
    annotated_frame = results[0].plot()
    cv2.imshow("Detection Results", annotated_frame)
    cv2.waitKey(0)

# Example usage
detect_objects('path/to/image.jpg')
🎥 Real-time Video Processing
import cv2
import numpy as np
from ultralytics import YOLO

def process_video_stream():
    # Initialize
    cap = cv2.VideoCapture(0)
    model = YOLO('yolov8n.pt')
    
    while True:
        ret, frame = cap.read()
        if not ret:
            break
            
        # Process frame
        results = model(frame)
        
        # Draw results
        annotated_frame = results[0].plot()
        
        # Display
        cv2.imshow('Real-time Detection', annotated_frame)
        
        # Exit on 'q' press
        if cv2.waitKey(1) & 0xFF == ord('q'):
            break
    
    cap.release()
    cv2.destroyAllWindows()
