Getting Started with AI Projects

Here is 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:
            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()
