A method of ear feature extraction for ear biometrics using MATLAB

摘要

Ear feature extraction is a crucial step of ear biometrics. Image preprocessing and normalization of ear image are very important steps of ear feature extraction. Ear recognition system still facing the problem of noise on the ear image. In this paper we have implemented a simple method to extract ear features using image processing which minimizes the noise problem in ear image. We proposed simple and less time consuming method for 2D ear feature extraction. For this we used MATLAB as a processing tool. We did image preprocessing to remove unwanted information of ear images, also performed steps like image segmentation and feature extraction to get desirable shape of ear for ear recognition system purpose.
