This paper presents the imaging solution for counterfeit and unfit coin detection based on extraction of unique segments on the reference image to be used for cross-correlation matching for validation, calculation of the diameter and thickness of coin and extraction of symbols from the “third” side of a coin or edge. The selection method of the unique segments to be used for cross-correlation is described...
In this paper simple in realization efficient imaging solution based on line-scan (1-D) camera and PC (with low-cost hardware) for euro coin recognition and validation has been proposed and investigated. Various approaches for image-based coin validation have been discussed. In proposed solution a 128-pixel linear image sensor of line scan camera with intelligent coin detection algorithm allows achieving...
