IMAGE PROCESSING BASED ON THE CROSS-CORRELATION MODEL

Dan HURGOIU, Vasile Tompa, Calin Neamtu, Daniela Popescu

Abstract


       The Kosons are ancient gold coins categorized as treasury coins which were not exchanged in commercial trades. This specific particularity of the Kosons enables scientists to use image processing techniques in the classification and authentication work. Because this type of coins have no signs of wear specific to a long time of circulation, it is now possible, by a rigorous inventory, to establish the number of molds used in the minting process. The only viable method for the identification and classification of an important amount of coins is a semi-automated or automated process. This paper presents the working algorithm and concepts implemented by the authors for Koson coins inventory, and also presents the hardware and software platforms designed for this application. The algorithm used to develop the software application is based on the Fast Fourier Transform (FFT) and Discrete Fourier Transform (DFT) applied in a correlation filter.

Keywords:  image processing, cross-correlation, gold Kosons, Dacian treasury
