Abstract

The invention relates to an iris identification method based on blanket dimension and lacunarity, belonging to the technical field of iris identification. The method comprises the following main steps of iris identification, iris image normalization, iris feature extraction and pattern matching. In the invention, the blanket dimension and lacunarity of iris texture are respectively calculated, and then two types of feature indexes are combined so as to obtain excellent identification effect; therefore, the method solves the problem that the existing iris identification method is incapable of efficiently utilizing iris fractal geometric feature and radiation physiological property.

Description

technical field

[0001] The invention relates to an iris recognition method based on blanket dimensions and missing items, and belongs to the technical field of iris recognition. technical background

[0002] Biometric identification technology is a method of identifying people by using their own physiological or behavioral characteristics. It has important applications in high-security fields such as airports, automatic teller machines, and e-commerce. At present, the features that have been applied to the field of biometric identification mainly include: fingerprints, palm prints, iris, hand shape, face, vein map, gait, etc. Among them, the iris has more unique advantages compared to other features. The iris is a fabric-like ring of colors inside the pupil of the eye, each iris contains a unique textured characteristic structure. The human iris is stable at about 2 to 3 years old and no longer changes with age. Because the iris has the advantages of high uniqueness, stab...
