Study on Parameters Setting of Chan and Vese Model to Iris Segmentation
Ying Chen, Fengyu Yang · 2015
Iris recognition plays an important role in personal identification.The first and critical step in the process of an iris recognition system is iris segmentation.In this study, several aspects are done.Firstly, the fundamental of Chan-Vese level set is described.Secondly, the process of related parameters setting of CV model is analyzed when CV model is used to pupil and iris segmentation.Finally, some conclusions are drawn.Some iris image from Institute of Automation, Chinese Academy of Science (CASIA) -V1 and CASIA-V3 Interval are taken as experimental samples.The experimental results show that appropriate parameters setting will help improve iris image segmentation effect.
