REVIEW ON THE COIN RECOGNITION SYSTEM WITH ROTATION INVARIANT?

This paper presents a reliable coin recognition system that is based on a polar harmonic transform. Coins are widely used in daily routine at various places like in banks, automated weighing machines, supermarkets, organizations for research purposes. So, there is a basic need to recognize the coin very accurately. There is problem that if coin is rotated at some angle then the system is unable to recognize it so we are going to introduce a new approach for rotation invariant for coin recognition that is if coin image is rotated at some angle it can be recognized and will prove rotation invariant. So, this paper focuses on removing the need of placing coin in particular position by using artificial neural network.
