Pixel Tracing Based Iris Segmentation

Student Initiatives & Projects - Student Projects
| Print |

In iris recognition system, accurate iris segmentation and localisation from eye image is the foremost important step. In this project, a robust and efficient method of iris segmentation is proposed.

Iris recognition systems have widespread applications including their use as a security system at airports, banks, vault entrances, study of various effects on irises of twins, as a segmentation method in other applications, etc.  Its purpose is real-time, high confidence recognition of a person's identity by mathematical analysis of the random patterns that are visible within the iris of an eye from some distance. Because the iris is a protected internal organ whose random texture is complex, unique, and very stable throughout life, it can serve as a kind of living passport or password that one need not remember but can always present.

 Because the randomness of iris patterns has very high dimensionality, recognition decisions are made with confidence levels high enough to support rapid and reliable exhaustive searches through national-sized databases.

This project has been done by Aman Bindal, Akhil Goyal and Ankuj Gupta, students of the Computer Science Division, graduating in the year 2010.

This project has been shaped under the guidance of Prof. Anand Gupta, an esteemed Graphics lecturer in the Computer Science division.

Many algorithms have been suggested for segmenting of iris but most lack either of these features: speed, accuracy, bounding the iris with circle only, etc. This project aims at designing an algorithm to overcome these limitations. 

The algorithm proposed by this project achieved speeds that were about ten times faster than the existing methods. Moreover, exact bounding of iris can be determined resulting in iris recognition systems that are more robust against fake-iris-based spoofing attempts. Furthermore, a high accuracy was achieved.

Their paper was published in the 2009 IEEE International Conference on Image Processing (ICIP) and in the 2009 International Journal of Critical Infrastructure Protection (IJCIP).

    The timely operation of street lights, porch lights and other forms of outdoor illumination is required for the twin concerns of safety and environment protection; lights operated too late are a safety hazard, while lights operated too early are a waste of power. The switching on and off of external lightings can be set with the help of the device twilight switch.Read more...

     Ever wondered how it would be if NSIT did not have a proper Placement Cell? Today we boast of an excellent student run placement cell but surprisingly none of us has ever thought about how students got involved with in the entire placement process. Who were the first students to work in the Placecom? If we ever ask these questions we would be surprised to know that the placement cell was started in 2006 and…

    Data is information that has been translated into a form that is more convenient to process. Data  is  often  viewed  as  a  lowest  level  of  abstraction  from  which useful information and knowledge are  derived. Experimental  data  refers  to  the  data  generated within  the  context  of  a  scientific  investigation  by  observation  and  recording. In an embedded system, data to be collected is either…

    The Neighbourhood Project is launching waste ED sheet collection drive to be given  away to Blind Schools through an NGO Goonj, to be used as Brailie books. The campaign has a huge potential in reaching out to the needy as one ED sheet costs 4 Rs, and is used in huge numbers by blind students. So please give out your used ED sheets to these people. ED sheets can be submitted in ED room on…
