Iris recognition method for protected site access control, involves simultaneously acquiring eye image in infrared and visible spectra, determining external boundary of iris, and extracting spectral distribution from visible spectrum image

摘要

The method involves acquiring an image of an eye in an infrared spectrum and in a visible spectrum e.g. red spectrum, simultaneously. An external boundary of an iris is determined from the image in visible spectrum. The image in infrared spectrum is processed for extracting identification characteristics from the iris delimited by the boundary on the eye. Spectral distribution is extracted from the image in the visible spectrum. An independent claim is also included for a device of recognition of iris.
