基于视频眼震图的瞳孔中心定位方法研究

Research on the Method of Pupil Localization Based on Videonystagmograph

瞳孔定位是计算机视觉领域一个重要的研究课题,涉及到生理学、心理学、人工智能、模式识别、计算机视觉、图像分析与处理等多个学科。对眼睛瞳孔中心的定位是用灰度聚类法粗定位虹膜中心,并用Canny算子进行边缘提取,然后利用Hough变换基于瞳孔的正圆特性精确定位瞳孔中心。

Pupil localization is an important research topic of computer vision field related to multiple disciplines including physiology,psychology,artificial intelligence,pattern recognition,computer vision,image analysis and processing,and etc.In this paper the positioning of the eye pupil center is that coarse positioning iris center with gray clustering and edge detection with the Canny operator,and then using the Hough transform based on pupil＇s orbicular characteristic to accurate positioning pupil center.
