Automatic ear detection and feature extraction using Geometric Morphometrics and convolutional neural networks
2017
Accurate gathering of phenotypic information is a key aspect in several subject matters, including
biometrics, biomedical analysis, forensics, and many other. Automatic identification of anatomical structures of
biometricinterest, such as fingerprints, iris patterns, or facial traits, are extensively used in applications like access control and anthropological research, all having in common the drawback of requiring intrusive means for acquiring the required information. In this regard, the ear structure has multiple advantages. Not only the ear's
biometricmarkers can be easily captured from the distance with non intrusive methods, but also they experiment almost no changes over time, and are not influenced by facial expressions. Here we present a new method based on Geometric
Morphometricsand Deep Learning for automatic ear detection and feature extraction in the form of
landmarks. A convolutional neural network was trained with a set of manually
landmarkedexamples. The network is able to provide
morphometric
landmarkson ears' images automatically, with a performance that matches human
landmarking. The feasibility of using ear
landmarksas feature vectors opens a novel spectrum of
biometricsapplications.
