New algorithm of iris location based on coordinate

A new and simple iris location method was proposed. The algorithm includes the location of inside and outside of the iris. Based on the rough process of the iris image, for the inside location the author takes the method of the projection to the coordinate, and for the outside the author looks for the point which the content of information is least on the scanning line. For the distribution of the yawp for example eyelash, the point which we choose is not only one. The author abandons the wrong point using the corresponding templates. It is proved that the algorithm is feasible through experiments.
