Pupil Localization Algorithm based on Hough Transform and Harris Corner Detection
Lian Zhang · 2016
In order to realize the pupil's positioning algorithm and solve the problem of complexity in the present stage, this paper hereby puts forward a kind of accurate location of the pupil from coarse to precise algorithm.Firstly, the position of the eye is located in the position of the human eye by grayscale integral projection; secondly, the precise position of the eye pupil center is detected by using the Hough transform.Finally the corner points are detected by Harris corner detection algorithm.The proposed algorithm is proved to be simple and accurate by MATLAB.
