Abstract

The invention relates to the technical field of iris recognition, and discloses a method for iris recognition. The method comprises the steps: collecting an iris image of a to-be-recognized object, and carrying out preprocessing of the iris image; performing iris positioning on the preprocessed iris image, and determining an iris effective area; sampling the iris effective area to obtain an iris matrix image corresponding to the iris effective area; performing feature extraction on the iris matrix image to obtain a plurality of iris features corresponding to the to-be-recognized object; and constructing a random forest classifier according to a plurality of decision trees, and performing iris recognition on the plurality of iris features through the random forest classifier to obtain an iris matching result. The technical problem of single feature of an iris recognition system is effectively solved, and the recognition rate and generalization ability of the iris recognition system are improved, so that the algorithm is more stable. The invention further discloses a device for iris recognition, terminal equipment and a storage medium.

Description

technical field [0001] The present application relates to the technical field of iris recognition, for example, to a method and device for iris recognition, a terminal device, and a storage medium. Background technique [0002] At present, the iris is a special physiological feature of human beings. It is concentrated in the circular area between the pupil and the sclera. This circular area is composed of very complex fibrous tissues, including many intertwined and interlaced small spots. , filamentous fibers, furrows, stripes, and crypts of various sizes. The iris is already formed in the developmental stage before the fetus is born. Except for some special eye diseases, the iris will basically not change and is very stable throughout the life course. Therefore, the above-mentioned detailed characteristics and invariance make each person's iris unique, and using the iris as the characteristic information of biometric identification and personal identity verification is uni...
