Machine Vision for Coin Recognition with ANNs download pdf

In this paper we have developed an parameters like diameter, thickness, weight and magnetism can ANN Artificial Neural Network based Automated Coin be used to differentiate between coins. The electromagnetic Recognition System for the recognition of Indian Coins of method based coin recognition systems improve the accuracy of recognition but still they can be fooled by some game coins.

We have taken images from both sides of coin. So this system is In the recent years coin recognition systems based on images capable of recognizing coins from both sides. Features are have also come into picture. In these systems first of all the extracted from images using techniques of Hough image of the coin to be recognized is taken either by camera or Transformation, Pattern Averaging etc.

Then, the extracted by some scanning. Then these images are processed by using features are passed as input to a trained Neural Network.

Wavelets [3], DCT, edge detection, segmentation, image only 2. Then based on these features General Terms different coins are recognized. Keywords 2. They performed experiments using yen coin and won coin.

In this work they have created a multilayered neural network and a 1. We use coins in our rotation invariance.

In this work they grocery stores etc. So there is basic need of highly accurate and efficient to design neural network for coin recognition. Adnan Khashman automatic coin recognition system.

In-spite of daily uses coin et al. ICIS uses neural network and pattern averaging the institutes or organizations that deal with the ancient coins. It shows M ohamed Roushdy [9] had M echanical method based systems used Generalized Hough Transform to detect coins in image. Electromagnetic method based systems In our work we have combined Hough Transform and Pattern Averaging to extract features from image. Then, these features Image processing based systems are used to recognize the coins.

In section 3 implementation The mechanical method based systems use parameters like details are given. In section 4 we have presented training and diameter or radius, thickness, weight and magnetism of the coin testing data.

Then, in section 5 the experimental results are to differentiate between the coins. Features are extracted from input data and used for object classification purposes. The performance of the networks is usually defined in terms of the classification accuracy. However, there are no real design guidelines for training and testing protocols.

This research set out to evaluate the effect on accuracy of the design parameters, including: size of the database, number of classes, quality of images, type of network, nature of training and testing strategy. A coin recognition task was used for the evaluation. A set of guidelines for part recognition tasks is presented based on experience with this task. Skip to main content.
