The Color Information as a Feature for Postage Stamps Recognition

Abstract

This paper describes the method of postage stamps recognition and the experiments carried out with it. It represents the basic operations of the post mail image processing. The article contains basic processing of the stamps image and calculation of characteristic features, on basis of which it will be recognized. The main objective of this article is to use the color information to obtain a set of features which are invariant under translation and rotation. The proposed method of recognizing can be applied in checking the value of post payments. The value of a post stamp is connected with a picture. The picture is represented in the color space where classification is done. The today’s systems of recognition often use classification on the basis of shape. Proposed method enables recognition of postal stamps from mail piece. Sources of errors as well as possible improvement of classification results will be discussed.
