Animal identification system based on irial granule analysis |
摘要 |
An animal identification system is provided which is designed to determine outlines of a pupil and irial granule in an input image of an eye of an animal to be identified, apply an arc to a lower portion of the outline of the pupil, turns back the arc from a principal axis to define a reference axis, and maps an image of the irial granule into a polar coordinate system whose origin is the center of the reference axis. The shape of the irial granule corrected in the above manner is compared with a reference shape stored in a memory to determine whether the input image arises from the same animal or not.
