We investigate object recognition and classification in a setting with a large number of classes as well as recognition and identification of individual objects of high similarity. Real-world data sets were obtained for the classification and identification tasks. The considered classification task is the discrimination of modern coins into several hundreds of different classes. Identification ...

Coins are integral part of our day to day life. We use coins everywhere like grocery store, banks, buses, trains etc. So it becomes a basic need that coins can be sorted and counted automatically. For this it is necessary that coins can be recognized automatically. In this paper we have developed an ANN (Artificial Neural Network) based Automated Coin Recognition System for the recognition of I...

Energy Dispersive X-Ray Fluorescence (EDXRF) technique has been used to study two Rupee Indian coins minted during the period 1993 to 2010 for their elemental concentrations. From the analysis of the coins, it is found that the coins are made of binary alloy and it was observed that from 2005 onwards, the composition of the coins has been changed from Cupro-Nickel to Ferritic Stainless Steel (F...

ion can overcome the deficit of the power of modern computers and solve the metaprogram problem: let’s consider amounts of coins instead of coin numbers. This idea is natural: when somebody is solving puzzles he/she operates in terms of amounts of coins of different kinds not in terms of their numbers! Let us present this hint in formal terms as an abstract model game(N,M) (N ≥ 1, M ≥ 0). Posit...

Automatic image classification algorithms can support coin experts in their analysis and study of coins. These algorithms take digital images of coins as input and generate a class as output. Automatic classification proceeds in two stages. In the feature-extraction stage, the image is transformed into a compact representation that contains information on the presence of features. In the classi...

For hundreds of years, supplies of coins in Europe emerged, via a curious mechanism, from voluntary decisions of owners of old coins and bullion to exchange them at mints for new coins. Mints were sometimes private enterprises, licensed to produce on demand a list of coins whose design and neness was speciied by the sovereign. Citizens were free to take metal to the mint 1 to purchase newly min...

 When an individual make a cash payment, he needs to consider about the amount to be paid, the coins and banknotes which are available and amount of change. For central banks and retailers, it is of interest to understand how this individual choice process works. The literature of currency use concerns primarily theory given certain assumptions which can present appreciate denomination r...

hundreds of stray coins are being donated every year to different iranian museums but it is difficult to establish their authenticities due to lack of knowledge about places of their findings. part of these stray metallic pieces is related to parthians. due to their lengthy rule, of about five centuries, parthian coins form important part of numismatic collection at the museums. authors have ta...

A COllective INtelligence (COIN) is a set of interacting reinforcement learning (RL) algorithms designed in an automated fashion so that their collective behavior optimizes a global utility function. We summarize the theory of COINs, then present experiments using that theory to design COINs to control internet traffic routing. These experiments indicate that COINs outperform all previously inv...
