Object Detector App

Abstract

1. Introduction

A real-time object recognition application using Google's TensorFlow Object Detection API and OpenCV.

2. Objective

Real-Time Object Recognition App with Tensorflow and OpenCV

This project demonstrates how Python, TensorFlow, OpenCV can be applied to a real-world AI & Machine Learning problem.

4. Technology Stack

5. System Requirements

General requirements for this technology stack — check the README for exact versions.

• Python 3.8 or later
• pip / virtualenv for dependencies
• VS Code, PyCharm or Jupyter Notebook
• Git (to clone the repository)

6. Installation & Setup

git clone https://github.com/datitran/object_detector_app.git
cd object_detector_app

1. conda env create -f environment.yml
2. python object_detection_app.py / python object_detection_multithreading.py
3. Device index of the camera --source=0
4. Width of the frames in the video stream --width=480
5. Height of the frames in the video stream --height=360
6. Number of workers --num-workers=2
7. Size of the queue --queue-size=5
8. Get video from HLS stream rather than webcam '--stream-input=http://somertmpserver.com/hls/live.m3u8'

Full setup instructions are in the project README.

7. Future Enhancements

Suggested extensions you can add to make this your own project.

• Deploy the model as a web app with Streamlit, Flask or FastAPI
• Compare against an additional model and report the metric difference
• Add explainability (SHAP / Grad-CAM)

8. Viva / Review Questions

Common questions examiners ask for projects in this domain.

1. What dataset does the project use and how was it pre-processed?
2. Which algorithm / model architecture is used and why was it chosen over alternatives?
3. How are training and testing data split, and how is overfitting avoided?
4. Which evaluation metrics (accuracy, precision, recall, F1) are reported and what do they mean here?
5. How would you deploy this model for real users?
