Research of Biometric Characteristics of the Shape of the Ears Based on Multi-Coordinate Methods

The chapter discusses modern methods of biometric identification of a person by the geometric shape of the ears. A method is proposed for analyzing the geometric shape of a person’s ear, which divides the image of the ear into regions and determines their area, and calculates the area of images belonging to the image of the ear and forms their references. The possible options for highlighting a separate image of the ear when scanning at a distance when other than the image ear itself contains images of hair and other neighboring parts of the human body are considered. The use of these methods requires the creation of a database with additional references for each person. For high quality identification, additional methods were used that are implemented on Radon projections. Software was developed that implements the method, which made it possible to carry out an experiment with databases obtained in random access from the Internet and formed by Esther Gonzalez. Experimental studies have shown high identification results for all used methods of preliminary processing of images and all simultaneously used methods of identification.
