Iris recognition is currently used by government offices and other agencies to refrain unauthorized personnel from accessing confidential information and control panels meant to be used only by the staff. Even consumer mobile appliances are equipped with iris scanners nowadays.

If you are unfamiliar with the Iris Recognition and want to learn more about it then you are in the right place because in this article I’ll explain what Iris recognition is, how it works, what it is used for along with some of its pros and cons. So let’s start without further ado.

What is Iris Recognition Bio-Metrics?

Iris Recognition is a method that helps in identifying people based on the peculiar qualities of their iris. The visible and near-infrared light scans the unique patterns and colors present within the ring-shaped part that surrounds the pupil of the eye, called iris.

The iris of every person is unique and different. Each iris contains unique, complex patterns and various colors i.e. brown, gray, blue, violet, and even green, etc that are visible. This is a form of biometric recognition that is why it is called Iris biometric recognition.

How Does Iris Recognition Work?

High-resolution IR camera is used to take a detailed and sophisticated picture of a person’s iris. The camera uses visible and infrared light to scan the eyelids, the edge of the iris, the center of the pupil and, eyelashes, etc.

Then the patterns and colors of the iris are encoded into digitalized information. This digital information is then analyzed by a program named matching engine that either compares the iris of the subject to the iris patterns stored in the database of the computer for verification or stores the information in its database for future identification.

Mostly the IR cameras are mounted on the wall however some applications of Iris Recognition are also portable. The subject has to identify themselves by scanning their iris in such cameras.

What is it Used For?

Until recently Iris Recognition was less common as compared to face and voice recognition because it required specific hardware installations. However, the recent advancements in biometric technology have made Iris recognition technology more accessible.

It is usually used as physical access security check-up in high alert security places i.e. airports, and border deployment. This technology is also used to prevent unauthorized people from accessing control rooms and labs in various facilities and government offices.

Other than that it is also very much in demand in the mobile phones and the markets of other electronics. Samsung’s Galaxy Note7, Lumina 950XL, and various Windows phones are equipped with Iris scanners that provide increased security to the user.

Pros

Iris Recognition software is superior to voice and face recognition because it is very accurate and efficient.

It has countless advantages and pros that make it a suitable choice for tons of companies and governmental departments. Below I’ll be listing some advantages of Iris recognition. 

1# Accuracy

Each individual has unique Iris and even the two eyes of one individual have different iris patterns. This contributes to the accuracy of Iris biometric identification.

Since the iris pattern of every person is unique, it is very hard to ditch the system. With Iris scanner, you can only be granted access if you are authorized personnel.

2# Contactless

It is necessary to be in close proximity to the iris scanner to allow it to scan and identify you. However, it is a contactless solution which makes it more hygienic as compared to other biometric solutions.

3# Flexible

Iris-Recognition is extremely efficient and flexible. It can even be used in the dark or at night because it uses an infrared camera.

It does not require adequate light as in face recognition. Since it is very flexible and scalable it has been used by the government and other agencies worldwide.

4# Liveness Detection

The advanced technology used in the iris scanner detects movement of the iris which identifies if the user is alive.

In short, it tries to gauge the liveness of the individual. This reduces the risk of unauthorized access through static images.

5# Fast Matching

It is one of the efficient, reliable, and fastest types of biometric identification.

Cons

Iris Recognition has several advantages but like everything else, it comes with some issues that need to be considered.

1# Distance

It might be a contactless technology but there is still a limit to the distance a person can stand from the iris scanner camera. This can be troublesome in some cases.

2# Movement

Even slight movement can be an issue with Iris-Recognition. The user has to remain as still as possible for the iris camera to work.

This is more of an issue with a handheld scanner as slight shaking of the hand can affect the scanning ability of the iris camera. The hand of the user has to remain steady so that the iris scanner can identify the iris.

3# Memory

It requires computer memory for data storage. However, advanced cloud-based storage solutions will solve this problem in the near future.

4# Costly

Iris biometric recognition can be more expensive than other forms of biometric identification because it requires the latest hardware and software solutions. Fingerprint and Facial Recognition are far more cost-effective and readily available.

Final Thoughts

Iris Recognition is the future of biometric recognition. There are tons of Iris-Recognition Projects that are working to improve the accuracy and functionality of iris scanners.

Soon, we’ll be seeing Iris scanner everywhere in place of the finger and face recognition biometric systems. So if you are looking forward to installing a biometric identification system, you should go for Iris Recognition.

Some trees grow at a slower rate as compared to others, but when you look around, you will find that many trees expand in a short matter of time. You will see such plants or trees making observable changes in a week or two.

It is difficult to believe, but many trees and plants around the globe are fastest growing than you could ever imagine. They increase in height and become tall in a year. So, what exactly are those trees? Read the latter and know for yourself.

Top Ten Fastest Growing Trees in the World

1. Bamboo

Bamboo expands in its height very quickly. Because of its unbelievable growth span, it is used in making sustainable and environmentally friendly products.

Bamboo can be easily replanted because of its incredible growth rate; only a single root-stock can give production of many horizontal shoots.

The shocking part is that some of its species can grow up to 10 centimetres in a single day, making it the fastest-growing tree.

2. Hybrid Poplar

The species of poplar are fast growing shade trees that can grow to a height at which a tree is ready for harvesting and use in the lumber industry as well. Amazingly, the hybrid poplar tree needs only a year to grow for about ten feet. Not as good as Bamboo, but still, the tree has gotten some potential.

3. Eastern Cottonwood

Eastern Cotton native to North America can grow incredibly in a year. In many areas, the tree can stand up to 10-15 feet per year and keeps on growing faster for a couple more years. After this phase, the tree keeps its pace and again grow for about 5 feet in a year continuing for a quarter of a century.

4. Red Delicious Apple Tree

There are more than 2,500 different species of apple trees cultivated in North America, but the red delicious tree is the most common one, maybe because of its mild flavor and long storage life. Red delicious is the fastest growing fruit tree with its height more than 24 inches per year.

5. Giant Sequoia

The species of sequoia have another incredible point; they do not only are considered to be the fastest-growing trees in the world but also have a size just like a mammoth. They extend about 4-6 feet per year for around ten years.

After that, they gain an extra 2 feet per year for another 30 years. Additional to their height, sequoias increase in circumference every year.

Some researchers studied General Sherman Tree and found out that the tree had three inches around its girth in just 40 years.

6. Acacia

Acacia can be regarded as the fastest growing tree because one of its specie, when planted in Sabah and Malaysia, had got surprisingly 35 feet in a short span of 13 months, which is equal to one inch per day.

Further, Acacia grows in a tropical climate where there is an abundance of nutrition and heavy rainfall throughout the year, that’s the reason acacia has a continuous growth rate.

7. Loblolly Pine

Loblolly pine is mainly used for timber, based in America. The tree continues to spread its beauty and ravishing green appearance throughout the year.

The natural range of loblolly pine widespread in the southeastern United States. The tree is distinguished among the other fastest growing trees with its large and columnar trunk, broad bark, reddish-brown plates having pale green needles.

8. Zelkova

Zelkova grows in a vase-shaped manner having smooth gray bark and red to purple color leaves that look so appealing and give autumn vibes.

The tree has 50-60 feet height making it one of the fastest-growing trees. Zelkova can be adapted to different weather conditions and can withstand wind and drought.

9. Red Maple

Red maple grows in a size of about 40-60 feet with its attractive red flower buds and blooms in the spring season.

Towards the end of spring and in the fall season, the tree turns to brilliant red colored leaves. Some species like Red Sunset or Northwoods have a branching structure and subtle fall color.

10. Pin Oak

Sounds strange? But yes, this oak is the fastest growing tree with a size of 60-70 feet. Pin oak has a pyramidal shape and has fine branches.

The shiny green leaves can turn into russet, bronze, or red-colored leaves in the fall season. The tree can withstand scarce conditions like acidic soil.

So, why wait? Pick some for your backyard.
