Nowadays, ancient coins are becoming subject to a very large illicit trade. Thus, the interest in reliable automatic coin recognition systems within cultural heritage and law enforcement institutions rises rapidly. Central component in the permanent identification and traceability of coins is the underlying image recognition technology. Prior to any analysis a coin image has to be segmented int...

Mixed-model U-shaped assembly line balancing problems (MMUALBP) is known to be NP-hard resulting in it being nearly impossible to obtain an optimal solution for practical problems with deterministic algorithms. This paper presents a new evolutionary method called combinatorial optimisation with coincidence algorithm (COIN) being applied to Type I problems of MMUALBP in a just-in-time production...

In the demonstration, we present a new system that performs fast and reliable classification digital photographs of coins. The system is called Coin-o-matic, and is capable of recognizing 700 different coins with over 2,000 coin faces. In its current version, Coin-o-matic classifies approximately 94% of the coins in our testsets correctly, whereas the percentage of misclassifications is around ...

Roman coins play an important role to understand the Roman empire because they convey rich information about key historical events of the time. Moreover, as large amounts of coins are daily traded over the Internet, it becomes necessary to develop automatic coin recognition systems to prevent illegal trades. In this paper, we describe a new large annotated database of over 2800 Roman coin image...

A few years ago, I acquired a gold coin of Kumaragupta I that had appeared in a CNG auction. 2 The cataloguer, saying it was a new variety, had dubbed the coin the “Lion Conqueror” type because of the extraordinary pose of the king, who stands triumphantly over the carcass of the lion he has presumably just killed. In fact, there is at least one other coin that shows the king in this posture, a...

Example 3. A coin toss is an example of a Bernoulli trial, which in general is an experiment with only two possible outcomes: success, which occurs with probability p; and failure, which occurs with probability q := 1 − p. Of course, success and failure are arbitrary names, which can be changed as convenient. In the case of a coin, we might associate success with the outcome that the coin comes...

We trust that the uncertainty regarding the outcome of a coin toss makes it a fair procedure for making a decision. Small differences in the force used to toss a coin should not affect this uncertainty. However, the voluntary movement involved in tossing a coin is subject to motivational influences arising from the anticipation of the value of the outcome of the toss. Presented here are measure...

With 3D scans, detailed models of both coin sides can be obtained which allow a more accurate analysis. When using virtual 3D models of a coin, high accuracy is a prerequisite for further coin documentation and coin identification processes. The difference between the original coin model and its virtual 3D model counterpart should be as minimal as possible. In this paper, we present an evaluati...
