The Algorithm Research of Coin Detection Based on DSP

With the widespread using of coins, in order to solve the troubles brought by counterfeit money, it is of great significance to develop a system for real-time identification of coins. In the analysis of image processing technology, the hardware and software in this field, this paper has verified the recognition algorithm in the MATLAB and VC, and it had set up an coin image processing system with the DSP chip as a platform. In this system not only the surface information of the coin can be achieved and processed in real time, but also a practical hardware and software basis for the further application of DSP for image processing can be built.
