IRIS RECOGNITION

The topic aimed to give the general ideas on how to identify the human by using the iris. The topic was well organized and presented to the class, Iris is the muscles within the eye that regulate the size of the pupil and controlling the amount of light that enters the eye. Iris recognition is the process of analyzing the randomly pattern of the iris.
Before the recognition the iris is located in the landmark features, localization of iris is important step in iris recognition because if it is being done improperly can result to noises. Also, require the use of high quality digital camera, but nowadays commercial iris cameras that use infrared to illuminate the iris without causing harm is used.
The vector on the iris is taken and are converted in the codes and then stored in 256 bits. The vector will give the position are of formation of the vector. This vector includes the information on the orientation and spatial frequency and the position of this area. Iris pattern are described by an iris code, using the phase information collected in phase. The polar coordinate systems included in the description of the iris are control bytes that are used to exclude eyelashes, reflection and other unwanted data.
The advantage of Iris recognition
1 Ease usage.
2 Certain conclusion ands minimum error rate.
3 Since the iris is unique, this ensures maximum security.
4 Identification of a persons who have limited use of hands or arms.
5 Is its stability, or template longevity.

Challenges of iris recognition-
• Distance scanning.
• Cost.
• Border control.
• Environmental challenges.
• High quality image

So far to recognize someone can be done the many other ways like speaker recognition, fingerprints and others using the iris recognition can be helpful in ensuring the security by identifying the real person.
