Abstract:
A multispectral iris recognition system includes a multispectral camera adapted to acquire spatially registered iris images simultaneously in at least three wavelengths and a database adapted to store the acquired iris images. A texture analysis section identifies an area within each acquired iris image having a maximum texture at each of the wavelengths. The identified areas are combined to generate an enhanced iris image. Additionally, a visible light iris image is acquired and stored along with a set of transformation mappings in a database. The acquired visible light iris image is modeled in a texture model, which clusters textures from the acquired visible light iris image. A mapping is selected from the database for each of the clusters. The selected mappings are applied to the acquired visible light iris image to generate a Near-Infrared equivalent.
