The basic idea behind the Real-Time Iris Identification approach is to identify a person’s iris based on some part of the iris that appears to change at a particular instance in time. That is the idea behind the 1D moving average filter that is based on 1D vectors or 1D matrices (e.g., sift descriptors). Because the distance of the center of mass of the human iris is a stable feature that appears in the same location in different views of the iris, it is used for identification purposes. This tutorial demonstrates how to build a stand-alone application for iris recognition with iris images captured by a smartphone camera and how to optimize the application for both memory and CPU. Please feel free to use the code in this tutorial for your own applications. Real-Time Iris Identification is a fast iris recognition system that works in real-time. This technique is different from the other method because it uses the mean value in order to identify the iris. For this reason, the algorithm is recursive, with increasing levels of detail. This tutorial demonstrates how to use the mean value to perform iris identification. For the coding part, we have made use of functions from the android.media.Image and android.media.ImageReader classes. However, the code is not fully self-contained. For this reason, the tutorial offers some definitions, which are used in order to perform the main steps in a more simple way. An eye image is formed by the reflections of light on the cornea, which acts as a lens. The iris, which is located in the front of the eye, can be seen in the iris image as an oval shape. An iris has 3 basic features, the pupil diameter, the iris circumference and the angle between the vertical line through the center of the pupil and the vertical line through the center of the iris. According to this tutorial, the pupil diameter and the iris circumference are the most important features for the iris identification. Real-Time Iris Identification uses an algorithm based on a moving average filter with a 1D vector. The procedure works as follows: Compute the mean value of the 1D vector. Create a second 1D vector by averaging the first vector and the newly calculated mean value. Repeat until the size of the vector is smaller than a given threshold (E.g. the iris is larger than 2.4cm). This approach can be used

KEYMACRO Description: Real-Time Iris Identification is a low computational approach for iris recognition 1D Moving Average Filter (MAF) is one of the most frequently used methods for iris recognition systems due to its robustness and small computational burden. However, the main shortcoming of MAF is that the shape and appearance of the pupil varies a lot between irises. This limits the generalization of an iris recognition system which is the main target of MAF. In this paper, we propose a new method called Real-Time Iris Identification (RII) for iris recognition. This method is mainly based on the use of 1D moving average filter (MAF). The algorithm is computationally very efficient and a new set of features for this type of filter have been defined. As in MAF, the main idea of RII is to use an average calculation for each pixel. However, instead of applying it after each pixel, we use the filter to calculate the mean values. In the first iteration, we consider an uniform window size and the mean value of the input pixels is calculated and the whole window is stored. At the second step, the size of the window is modified to the next nearest neighbor (NNN) pixels. Then, the mean value of the NNN pixels is computed and the window moves to the next NNN pixel and so on. This recursive calculation process continues until it reaches the last pixel. In this way, a 1D moving average filter with a NNN window size is defined and the mean value of all pixels is calculated. In our experiments, this approach achieved a high level of accuracy (99.3% for the database Extended Yale B), compared with previous works (Hamdy et al., 2004; Hamdy, 2005; Xie et al., 2005). Computational Time: The overall computational time of the system was measured in terms of number of operations per frame for both the RII method and the MAF method. Using Matlab/C++ programming languages the computational time was measured by running 10 series of frames in each method. The length of the template was set to 128 with the NNN window size set to 5. The sampling rate was set to 50 fps for both methods. All images were stored in a Matlab file which was a greyscale image of 320 × 240 pixels with 32 bits per pixel. The results of both methods are shown in Tables 1 and 2. Using Matlab/C++ programming languages the computational time was measured by running 10 series of frames in each method.

It is based on processing of an image of the iris pattern of the eye. Iris recognition is not restricted to a certain group of people such as a national identity card. Iris recognition has recently gained great interest for personal identification and access control. It is used in public security applications and commercial airports. One of the best features of Iris recognition is that it is easy to implement and to use in real-time. This makes it suitable for many practical applications. Because of its popularity, iris recognition is now being used in more and more applications. In the near future, it may be used for access control, identity and medical purposes. This presentation will describe the development of an iris recognition system for a driver license. The system works in real time. We will describe the main characteristics of the system, the procedure to extract the iris features and the process to match the features with reference information. An iris recognition system must be tested to ensure that it can properly identify the iris of an unknown person. This requires a large number of tests on different people. For these tests, an automatic recognition system is not always optimal. In a more general context, the system will be tested against iris images of different persons. In these tests, the system may be asked to select the person or it may be required to perform the iris recognition. The presentation will also show how the main characteristics of the system (such as the recognition rate, the false acceptance rate and the false rejection rate) can be computed automatically. Shannon showed that in order to correctly identify a random variable, a function of its probability density must be known. A number of applications are known where this knowledge is not available. The probability distribution function must be estimated in these cases. The term "estimate" is widely used in statistics. In this presentation, we discuss the concept of sample mean. This notion will be extended to other statistical estimators. The sample mean of a finite number of real numbers is not sufficient to estimate the mean of a random variable. Because of this, the concept of probability density function is introduced. The probability density function is the mathematical function that gives the probability of finding a certain value of the random variable at a given point. The density function is a particular case of the probability distribution function. The density function is a function of the random variable. It describes the behavior of a single realization of the random d408ce498b Real-Time Iris Identification is a low computational approach for iris recognition based on 1D moving average filter.
