an indian coin recognition matlab code
The objective of this paper is to classify the Indian coins of different denomination released recently. This paper is framed mainly to classify the coins offered in the Hundi by the devotees of Tirumala Tirupati Devasthanam(TTD), Tirupati, India. The objective is to count money by recognizing the coins and count the total sum based on its value. The system is proposed to design coin recognition by applying heuristic approach, based on the coin table. This table stores parameters of each coin. This method yields 97% of result in recognizing the coin image. It is also proposed to apply HT algorithm combining the features of a) Straight line detection HT algorithm, b) Curve detection HT algorithm and c) Circle detection HT algorithm. Using these three algorithms edge of the coin is recognized. The features of old coins and new coins of different denominations are considered for classification. Some coins are used in different countries have same parameters, but it has different value. This paper concentrates on affine transformations such as simple gray level scaling, shearing, rotation etc. The coins are well recognized by zooming processes by which a coin size of the image is increased. This paper presents a coin recognition method with rotation invariance. Indian Coins are classified based on different parameters for various values of coin such as shape, size, surface design, weight and so on. Hence, it is easy for the automatic machine
to classify Indian coins.. There are many coin classification machines are available, but , the machine has to be designed for recognition of Indian coin. To increase the efficiency of the machine, they are to be embedded with proper source code.In this paper, Sobel Filter, HA and HT are used to classify the coin image. It is proposed a method for realizing a simple automatic coin recognition system more effectively. The HT technique is used to recognize almost 100% of the coin image. Comparing to Sobel edge detection method, HA the HT gives better result.
