A robust iris localization scheme for the iris recognition
Multimedia Tools and Applications, 2020Due to current security situations around the globe, iris biometric technology is highly preferred for both overt and covert applications. A typical iris biometric system includes image acquisition, iris segmentation, features extraction, and matching and recognition modules.

A study of a human recognition by use of biometrics known as Iris Recognition is provided. Based on the technology invented by Dr. John G. Daugman, an attempt of implementing a workable system was made. Although the attempt did not succeed in every aspect, “Iris Recognition” is forecast to play a role in a wide range of other applications in which a ...

Proceedings. International Conference on Image Processing, 2003
The principle that underlies the recognition of persons by their iris patterns is the failure of a test of statistical independence on texture phase structure as encoded by multiscale quadrature wavelets. The combinatorial complexity of this phase information across different persons spans about 249 degrees of freedom and generates a discrimination ...

Effects of iris surface curvature on iris recognition
2013 IEEE Sixth International Conference on Biometrics: Theory, Applications and Systems (BTAS), 2013To focus on objects at various distances, the lens of the eye must change shape to adjust its refractive power. This change in lens shape causes a change in the shape of the iris surface which can be measured by examining the curvature of the iris. This work isolates the variable of iris curvature in the recognition process and shows that differences ...

Detection of Non-iris Region in the Iris Recognition
2008 International Symposium on Computer Science and Computational Technology, 2008In view of iris disturbance of eyelid, eyelash and reflection spot affect the accuracy of iris recognition, a detection approach of non-iris region in the iris segment is proposed. Based on mathematical morphology knowledge, the proposed method uses the least squares combined with edge detection to determine eyelid occlusion, then, eyelash and ...

3D iris structure impact on iris recognition
2015 23nd Signal Processing and Communications Applications Conference (SIU), 2015The accuracy of iris recognition systems depends on several factors such as the quality of data capture, camera angle, pupil dilation. In standoff iris recognition systems, a new biometrics research area, corneal refraction of light, depth of field blur, and the limbus effect are previously addressed as degradation factors for the iris recognition ...

Efficient approach for iris recognition
Signal, Image and Video Processing, 2016Iris texture is a natural password that has great advantages such as variability, stability, unique features for each person, and its importance in the security field. This makes an iris recognition system upper of other biometric methods used for human identification. Recent science is interested to develop intelligent systems able to identify persons

A NEW APPROACH TO IRIS RECOGNITION
International Journal of Information Acquisition, 2007Iris recognition technology relates to computer vision, pattern recognition, statistical inference, and optics etc. Because the randomness of iris patterns has very high dimensionality, it is difficult to find an efficient approach to iris recognition.

A Novel Iris Recognition System
2007 Third International IEEE Conference on Signal-Image Technologies and Internet-Based System, 2007Iris recognition as an emerging biometric recognition approach and itpsilas becoming a very active topic in both research and practical applications. The pattern of the human iris differs from person to person, even between monocular twins. This paper proposes a modified iris localization method and normalization method.

Quality based iris recognition
3rd International Conference on Imaging for Crime Detection and Prevention (ICDP 2009), 2009The widespread interest in personal identification has increased the need for an accurate and efficient ways of identification, verification and authentication. Biometric-based personal identification systems have proven their superior performance. These systems rely on the person physiological traits such as the iris, fingerprint or face, etc.
