A practice of verifying people’s identity by unique patterns of the iris is called iris recognition. These patterns are collected from the ring-shaped area over the eye pupil. In general, the iris region is in blue, green, and brown color along with complex patterns. Further, it helps you to perform a close investigation of the biological features of the iris region. Overall, it is best to identify the person identification using biometric authentication. This page is completely created for helping PhD / MS scholars or Final year students who wish to do iris recognition project using python!!!

Generally, an iris recognition project takes two or more iris images as input. In specific, these images are captured by high-resolution digital camera at IR / visible light. Next, it performs a sophisticated computer-assisted matching technique. This technique compares patterns of the input image with the already stored image in the database. By the by, the matching engine has the ability to compare millions of images without compromising quality. So, it is efficient than other traditional techniques.

Implementing IRIS Recognition Projects using Python code

What are the four steps for an iris recognition system?

The fundamental steps involved in iris recognition system are four such as image collection, iris separation, feature extraction, and pattern matching. Among other biometric authentications, iris recognition is considered to be the most accurate person’s identification. Although it is treated as the best technique, it has few research challenges in implementing iris recognition in real-world scenarios. Some of the primary limitations of the iris recognition system are given as below,

Limitations of Iris Recognition

Localization of Eye Pupil Border / Inner Edge
Reduction of Specular Reflection
Minimization of Noise Eyelid, Eyelash, etc.
Localization of Iris Outer Edge

Now, we can see the important algorithms to identify complex iris patterns in any format of iris images. Each has a set of instructions to solve specific research problems. Here, we have also included the main purpose of each algorithm in iris recognition.

Majorly, it involves preprocessing, iris segmentation, feature extraction, and pattern matching to detect iris in biometric authentication. Specifically, each process is suggested with multiple algorithms and techniques. So, it is necessary to compare the purposes and efficiency of algorithms in advance of techniques confirmation.

For illustration purposes, here we have taken “feature extraction” as an example. In this, we have highlighted all possible research solutions that are effective to extract essential iris features/patterns. Likewise, we also have a list of techniques for other key operations of iris recognition. One should choose the right algorithms for their proposed research issues based on their project objectives. If you are new to this field, then we are ready to guide you appropriately in your required phase of research.

Feature Extraction Methods for Iris Recognition

Scale-invariant Feature Transform (SIFT)
Principal Component Analysis (PCA)

Next, we can see significant python libraries used for iris recognition. Generally, Python is a scripting language that supports various libraries and functions for different image processing operations. These in-built libraries are efficient to implement both conventional and modern techniques. For instance, python is capable to support any sort of complex mathematical task using “math” library. Similarly, it collects several libraries which is easy to import into the developing project. Moreover, each library has a specific set of operations that are used for satisfying the requirements of the iris recognition system.

Imported Libraries in Python for Iris Recognition

import os
import sys
import cv2

import cPickle

Then, we can see a basic module that is widely used to implement iris recognition project using python. As well, it is said to be a G6_iris_recognition module which is highly preferred by developers. This package includes numerous math functions and libraries that support all sorts of image processing operations. By the by, it also helps you to develop a secure and fast iris detection solution.

For your reference, here we have given you the installation command, packages needed to be installed, and supported operating system. Likewise, we also give software and python package installation procedure at the time of project delivery.

In addition, we have also shared with you the procedure to use python packages over the iris recognition system. In this, we have mentioned packages for both training and testing of iris images until acquiring the name of matched patterns person.

Beyond this, there are loads of packages in the iris recognition project using python. Our developers are efficient to choose the appropriate package based on your project needs. Our ultimate goal is to minimize the number of code lines with accurate results.

How to use Python Package for Iris Recognition?

When all the required settings and configurations are made, import G6_iris_recognition module to begin your project execution.
import G6_iris_recognition
After completion of the import process, train input image collected from Input_database Folder
- Input_database/
Then, train the encrypt module based on the below procedure
- G6_iris_recognition.iris_model_train(train_DB_path,train_Encode_model_path)
- train_DB_path – Input_database/
- train_Encode_model_path – encodingModel/irisEncodings.pickle
When the training process is completed then move on to the test process using real-time images
- iris_name=G6_iris_recognition.iris_model_test(test_Encode_model_path,real_world_image_path)
- test_Encode_model_path – encodingModel/irisEncodings.pickle
- real_world_image_path – real-time_image_path
Return person’s name (if matches found, then return person’s name)
- iris_name

Further, we have also listed out few key requirements of iris recognition. Most importantly, python is furnished with numerous libraries and modules for efficiently processing millions of images. These are the main reasons that developers are choosing python to implement iris recognition.

To process images, collected images also need to satisfy the following requirements. Since it helps to process images with high accuracy and high speed. We ensure you that we strictly fulfill all these needs before processing images.

Python Requirements for Iris Recognition

Capture images without direct sunlight
No sunglasses or lens are allowed in images
Require flawless images from the scanner
At least require 90% of eye iris image
For the training process, at least 5 clear images are needed
Follow same resolution/size for all scanned images
Alter parameters based on image noise, size, and quality
A set threshold value for matching hamming distance

Iris recognition project using python takes 2 IR eye images as input and generates a matching score. If the matching score matches the threshold value then it is recognized as the same person. Further, we have also given you a step-by-step procedure to develop an iris recognition system using OpenCV. In our procedure, we also include the dataset, research problems with corresponding solutions, performance metrics, and system requirements. Further, all our recommended libraries and modules are efficient to implement the iris recognition system in simple manner.

- Train CASIA iris image database, it comprises nearly 16000 eye images
- These images are collected from 400 individuals
- By this process, we perform 50000 test samples
Localization of Iris

- Then, it encrypts important features of every iris
- Next, implement SIFT algorithm using OpenCV in order to relate features

Classification
- When the matching score is equal to the threshold, the iris is detected as the same person
Performance Evaluation
- When there is no match among images, the false accept rate is 0
- When there is 95% match is found, a false reject rate is 5%

In addition, we can see datasets of the current iris recognition project using python. In the development phase of research, dataset selection is very vital similar to development tool and performance metrics selection. Since iris recognition is considered a data-intensive application which majority of processes are based on dataset. Therefore, take extra care while selecting dataset for your project.
