Abstract

In the article we present discrete geometrical algorithms of open contours representation, feature extraction and recognition. The proposed algorithms were developed for ear biometrics, but they can be also applied in other contour image processing applications. Firstly we present mathematical and algorithmic foundations of our geometrical feature extraction methods. We also discuss their application and the achieved results for ear contour image analysis and recognition.
