Iris Recognition Technology
The Iris
Iris had many features which is used to distinguish one iris from the other. There was no genetic influence while developing the iris, this process is known as "Chaotic morphogenesis" which will occur during the seventh month of the gestation. Even twins will have different type of irises. The iris is secure behind the eyelid, cornea and will be aqueous, which means unlike the other biometrics as fingerprints..etc. The iris will not change in subject of age this will always remain constant till the death. The use of the contact lenses and glasses will have a little effect on the representation of the iris and this will not obstruct with the recognition technology. The below picture will show the variation of irises.

There will no two similar iris will exist, once an iris will come into being, then this will remain unchanged for the entire life. This iris is very difficult to falsify, and user do not need to make any physical contact with the device while capturing the image.
Process of recognizing Iris:
The procedure of capturing the iris into the biometric is made in three steps.
1. Capturing the image
2. Defining the location of the iris and optimizing the image
3. Storing and comparing the image.
1. Capturing the Image
The Iris image is just captured with the standard camera by using both the visible and the infrared light either by a manual process or an automated process. The camera is placed between three and a half inches and along one meter to capture the image. In getting the manual process the user must adjust the camera to get the iris in focus which needs to be in between six to twelve inches of the camera. This process is more manual and it al...

...yed as errors. The point at which the FAR and the FRR are equal are known as Crossover Error Rate (CER). If the CER value is lower than the system will be more accurate and reliable. If the Hamming Distance is .342 in the Iris Technology then it is nominal CER.
System Usage:
The usage of the iris technology is very fast. The capturing and the testing of the images is very fast, it must require some training. The glasses must be removed during the enrollment in the recognition system will ensure the best image will be captured without any reflections from the glasses or the lenses.
The comparison of the live Iris Code and the recorded Iris Code in the database may seem like a large amount of the data to process, but coming to reality this will take a very few seconds. The comparison speed is the speed of the processor it is not dependent on the size of the database.

Heterochromia Iridis is the Greek term for “differently colored irises”. More popularly known as just heterochromia, as the term is described two different-colored eyes that are on the same being. Heterochromia is most commonly found in cats. Instead of calling the condition heterochromia, the term often used for cats is “odd-eyed”. Along with heterochromia, however it has been supposedly known to be linked to other disorders, such as deafness making odd-eyed cats can be more vulnerable to. While heterochromia is usually present when the disorder; deafness is found, heterochromia in cats does not stimulate hearing loss than normally would, because how the mutation develops doesn't contributed to the linked condition, the certain breeds who are more susceptible to heterochromia along with the other associated disorder, and one known condition (hearing loss) linked to cats with heterochromia.
by the internal computers of the instrument, to create an image of internal body tissues. These images were then displayed on the screen for the user,
It is easy to think of biometrics as the future science technology are always happened in some fictions, associated with solar car and clones together. In fact, it has long history that people understood the basic principle and application of the biometric. Thousands of years ago, the people of the Nile basin used the biometric in everyday transactions (such as scarring, skin tone, eye color, height, etc.) for identification. Of course, they had no any automatic electronic identification system, or computer network, but the principle is similar.
The iris acts to control the size of the pupil. In bright light, the iris is dilated in such a way as to reduce the size of the pupil and limit the amount of entering light. In dim light, the iris adjusts its size as to maximize the size of the pupil and increase the amount of incoming light.
Biometrics is described as the use of human physical features to verify identity and has been in use since the beginning of recorded history. Only recently, biometrics has been used in today’s high-tech society for the prevention of identity theft. In this paper, we will be understanding biometrics, exploring the history of biometrics, examples of today’s current technology and where biometrics are expected to go in the future.
Now for our eyes we use them for vision, their like our own personal camera’s,

Albinism affects people of all races. Most children with albinism are born to parents who have normal hair and eye color from their ethnic backgrounds. Albinism is found on the eleventh chromosome, section q, loci 14-21. Oculocutaneous albinism involves the eyes, hair, and skin. Ocular albinism involves primarily the eye.
When testing the twins research shows that there IQ different at first. Then after doing the IQ test a few times they began to rise and become closer to the same
Measuring devices in the laboratory as well as in some industries mostly have a display unit through which the output is taken. The process of output data collection from display is usually done manually or by data acquisition cards which may not be always available. Moreover, commonly available data acquisition cards are very costly. So a solution of this data acquisition problem is proposed using a webcam and processing unit which can be arranged for at a nominal cost. Further it can eliminate the error of human eye as well as adjust the interval of taking the reading.
The purpose of biometrics is to identify a person based on the measure of his anatomical and physiological characteristics. This concept is not new, its history dates back to 14th century when Chinese used footprints to identify newborns and divorce records. In the 1880s, Henry Faulds, William Herschel and Francis Galton were the first who conceived the idea of using biometric identification to guaranty the security in civil areas, like using footprints for criminal identification and fingerprinting t...
...he cornea is deformed so that its surface is oval instead of spherical. Light rays are distorted at the entrance of the eye. This produces a blurred image and is known as astigmatism. To correct it, glasses are given a nonspherical or cylindrical curvature. Cross-eyes and walleyes are produced when both eyes do not work together because of weakness of the eye muscles.
