Why real-time object detection matters in Algeria

Road accidents remain one of the most critical safety issues in Algeria.
Fast highways, crowded intersections, busy pedestrian crossings, and inconsistent road signage make computer vision a necessity.

Real-time object detection helps:

• Prevent accidents
• Monitor traffic conditions
• Power smart-city infrastructure
• Enable ANPR, lane monitoring, traffic violation detection

Models like YOLOv4-Tiny (extremely fast) and YOLOv8 (modern and accurate) allow you to deploy real-time AI systems using nothing more than a laptop and a camera.

What is real-time object detection ?

Real-time object detection is the process of identifying objects inside a video stream fast enough to keep up with live movement.

In the Algerian context, this matters because it enables:

• Traffic monitoring
• Road-safety automation
• Highway analytics
• Smart transportation systems

A real-time system must provide:

• 15–60 FPS performance
• Low latency
• Lightweight and efficient models

Tools you need

Here’s the essential toolkit to get started:

Core tools:

• Python 3.8+
• OpenCV
• YOLOv4-Tiny
• YOLOv8 (Ultralytics)
• A webcam / USB camera / IP camera

This setup is fully enough to run high-speed inference on Algerian roads (Algiers, Oran, Constantine, etc.).

Preparing your dataset

A strong dataset is the foundation of a strong model.

Algerian data sources

• Your own dashcam or smartphone footage
• ADET datasets
• RoboFlow Algerian traffic datasets
• Recorded urban and highway videos

You can check these links :

• Vehicles traffic recordings on public road (Oran, Algeria) – Mendeley Data.
• Dataset of traffic signs and lights, reportedly including Algerian roads.
• Algerian License Plate 500 Dataset
• General traffic / road‑traffic / video datasets on public CV platforms (from e.g. other public datasets, global traffic datasets)

Note : Make sure to anonymize faces and license plates if needed.

Labeling tools

• LabelImg (simple, fast)
• CVAT (collaboration, powerful)

Best practices

• Use simple classes: car, bus, pedestrian, traffic sign
• 500–3,000 images are enough for a small custom model
• Include diversity: day/night, rain, highways, roundabouts
• Use an 80/20 train-test split

Setting up your environment

Install dependencies:

pip install opencv-python ultralytics numpy

For YOLOv4-Tiny, download:

• .cfg file
• .weights file
• .names file

Test your webcam

import cv2

cap = cv2.VideoCapture(0)
while True:
    ret, frame = cap.read()
    cv2.imshow("Webcam", frame)
    if cv2.waitKey(1) & 0xFF == 27:
        break
cap.release()
cv2.destroyAllWindows()

Running YOLO models (Inference code)

YOLOv4-Tiny inference code

import cv2
import numpy as np

net = cv2.dnn.readNet("yolov4-tiny.weights", "yolov4-tiny.cfg")
classes = [line.strip() for line in open("obj.names")]

cap = cv2.VideoCapture(0)

while True:
    _, frame = cap.read()
    blob = cv2.dnn.blobFromImage(frame, 0.00392, (416,416), swapRB=True)
    net.setInput(blob)
    outs = net.forward(net.getUnconnectedOutLayersNames())

    for out in outs:
        for det in out:
            scores = det[5:]
            class_id = np.argmax(scores)
            conf = scores[class_id]
            if conf > 0.5:
                x, y, w, h = det[0:4] * np.array([frame.shape[1], frame.shape[0], frame.shape[1], frame.shape[0]])
                cv2.rectangle(frame, (int(x-w/2), int(y-h/2)), (int(x+w/2), int(y+h/2)), (0,255,0), 2)

    cv2.imshow("YOLOv4-Tiny", frame)
    if cv2.waitKey(1) == 27:
        break

YOLOv8 inference code

from ultralytics import YOLO
import cv2

model = YOLO("yolov8s.pt")
cap = cv2.VideoCapture(0)

while True:
    ret, frame = cap.read()
    results = model(frame, conf=0.5)

    annotated = results[0].plot()
    cv2.imshow("YOLOv8", annotated)

    if cv2.waitKey(1) == 27:
        break

Optimizing your real-time pipeline

Pipeline steps

1. Capture frame
2. Preprocess
3. Run inference
4. Draw bounding boxes
5. Render output

Performance tips

• Use GPU acceleration (CUDA) if available
• Lower input resolution (e.g., 320×320)
• Prefer YOLOv4-Tiny on low-power devices
• Enable frame skipping
• Use multithreading for capture + inference

Expect 15–40 FPS depending on your hardware.

Use cases in Algeria

Real-time object detection unlocks valuable applications for smart mobility:
