轮廓初始点检测对眼睛虹膜区域反射光的去除
Eye corneal reflection removal based on boundary initial position detection
摘要
Abstract
Corneal reflection removal is a critical step for an iris recognition system because it directly affects the gaze detection and tracking. Due to the different luminous environment, the model of the corneal reflection is not a regular circle. So an irregu-lar shape of corneal reflection should be considered to detection and removal. In this paper, it focuses on reflection boundary which involves in iris region and it proposes a new method to locate the corneal reflection based on intensity gradient and tex-ture gradient features. Also, in order to narrow the detection scope, it proposes to extract the iris region via detecting the iris cen-ter which based on color image segmentation, vertical edge operation and curve fitting. The result shows that the technique per-forms well, especially, to detect the salient reflection boundary. The proposed method is robust and applicable on various kinds of eye image with different eye center location and noise properties.关键词
