Pupil and Iris Localization for Iris Recognition in Mobile Phones
Seventh ACIS International Conference on Software Engineering, Artificial Intelligence, Networking, and Parallel/Distributed Computing (SNPD'06), 2006Until now, iris recognition has been used in many fields. Recently, there have been attempts to adopt iris recognition technology for the security of mobile phones. For example, in case of bank transaction service by using a mobile phone, using a mobile phone can use high level of security based on iris recognition.

Pupil Center Localization Using SOMA and CNN
2019We present a new method for eye pupil detection in images. The algorithm runs in two steps. Firstly, a reasonable number of good candidates for pupil position are determined quickly by making use of the self-organizing migrating algorithm. Subsequently, the final position of pupil, among the preselected candidates, is determined precisely by making use

Automatic localization of pupils in color human images
Proceedings of 2004 International Conference on Machine Learning and Cybernetics (IEEE Cat. No.04EX826), 2005In this paper, a simple and applied approach was presented, which can automatically locate pupils. On the basis of skin detection of human face, it combines such techniques as edge extraction and geometrical features to confirm the coarse eye regions with ways of gray integration projection, region combination and LAT to fix on the precise location of ...

Pupil Localization Using Geodesic Distance
2018The main contributions of the presented paper can be summarized as follows. Firstly, we introduce a unique and robust dataset of human eyes that can be used in many detection and recognition scenarios, especially for the recognition of driver drowsiness, gaze direction, or eye-blinking frequency.

Localization of the pupil trigger in insect superposition eyes
Journal of Comparative Physiology A, 1992In the superposition eyes of the sphingid moth Deilephila and the neuropteran Ascalaphus, adjustment to different intensities is subserved by longitudinal migrations of screening pigment in specialized pigment cells. Using ophthalmoscopic techniques we have localized the light-sensitive trigger that controls pigment position.

Application of Masking and Ellipse Fitting in Pupil Localization
Advanced Materials Research, 2013The human eyes feature plays an important role in the human face feature extraction and the human face recognition. It can be used to correct the human face posture and locate the other face key features by the coordinates of the eyes on the human face.

Iris localization: Detecting accurate pupil contour and localizing limbus boundary
2010 2nd International Asia Conference on Informatics in Control, Automation and Robotics (CAR 2010), 2010Iris-based recognition system is highly dependent on the accuracy of iris localization. In this paper, a new algorithm for iris localization is presented, it detects the precise pupil contour and localizes limbus boundary. The pupil boundary is first localized by fitting a circle to the set of pupil boundary points detected by using the angular ...

Combining isophote and cascade classifier information for precise pupil localization
2016 IEEE International Conference on Image Processing (ICIP), 2016This paper investigates precise pupil center localization in low-resolution images. Being an essential preprocessing step in many applications such as gaze estimation, face alignment as well as human-computer interaction, robust, precise, and efficient methods are necessary. We present a method for accurate eye center localization operating with images
