  • University research projects

  Getting Started with AI Projects

  Here’s a simple object detection example using OpenCV and a pre-trained model:

  
  import cv2
  import numpy as np
  
  # Load pre-trained model (MobileNet SSD)
  net = cv2.dnn.readNetFromCaffe("deploy.prototxt", "mobilenet.caffemodel")
  
  # Capture video from camera
  cap = cv2.VideoCapture(0)
  
  while True:
      ret, frame = cap.read()
      blob = cv2.dnn.blobFromImage(frame, 0.007843, (300, 300), 127.5)
      net.setInput(blob)
      detections = net.forward()
  
      for i in range(detections.shape[2]):
          confidence = detections[0, 0, i, 2]
          if confidence > 0.5:
              # Draw bounding box
              box = detections[0, 0, i, 3:7] * np.array([frame.shape[1], frame.shape[0], frame.shape[1], frame.shape[0]])
              (x1, y1, x2, y2) = box.astype("int")
              cv2.rectangle(frame, (x1, y1), (x2, y2), (0, 255, 0), 2)
  
      cv2.imshow("Object Detection", frame)
      if cv2.waitKey(1) & 0xFF == ord('q'):
          break
  
  cap.release()
  cv2.destroyAllWindows()
