Due to the poor anti-jamming ability of traditional gray projection method,we propose a new method based on region projection for precise eye localization.Firstly,taking the two-dimensional characteristics into account in the process of projection,the eye image was divided into several non-overlapping regions,and the candidate region of pupil was obtained by horizontal projection and vertical projection.The region was expanded and a pupil window was got.Then,the pupil center was localized exactl...
