Overview

Student ID Card Recognition is my AI's project for scanning and extracting information from DUT's Student ID Card with Image Processing and state-of-the-art Deep Learning's model (YOLO + Transformer).

Application

Student ID Card Recognition can be applied with License Plate Recognition to build a parking lot for Da Nang University of Technology.

System

Technologies

• Image Processing with OpenCV
• Object Detection with YOLOv4-tiny
• Text Recognition with Transformer
• Flask-Python to create API and build website
• Docker for deployment

Features

Current features:

• The main function of system is to identify and extract information from Student ID Card photo. Users can upload a card image to the system, and this system will return extracted information from the photo, for example:
  • ID Number
  • Full name
  • Class name
  • Date of birth
  • Faculty
  • Year

To-do list:

• Use an Object Detection model (YOLO, SSD, etc) for scanning ID Card in the input image instead of using Image Processing.
• Add one more function to this system: Vietnamese ID Card Recognition

Performance

Because I don't have a server with GPU, so the processing time is quite long. The average processing time is:

• Server without GPU(4 Cores, 4 GB RAM): 2 - 5 seconds/photo.

Requirements

• The input image must have 4 clear angles and its background should be white or gray and not contain anything else :disappointed_relieved: to make sure the ID Card can be seen.
• All information fields must be visible, readable, unmodified and not blurred.
• The input image size does not exceed 5 MB, and the minimum resolution is approximately 640x480 to ensure the confident rate.
• The ratio of Student ID Card area must be at least ²⁄₃ of the total image area.

How to test

This website is temporarily unavailable because my Azure account has no credit to keeping this service 😅

I have built a simple website to show how it works. However, to use this website you need a Student ID Card as your input image. So, please download the test-img folder then use one of them. Sorry for this inconvenience 😞

Status

Project is no longer continue because I'm dying with my mind 😢
