The ACCA Research Lab

ACCA was established in2005 and, along with the National Science Council of the Executive Yuan and the Graduate School of Marine Engineering at NTOU National Taiwan Ocean University’s, it embarked on a research project entitled “Coin Appraisal Research—Detecting Forged Coins Using Artificial Neural Networks”. Then in 2006 and 2007 respectively, it completed the 2 stages of a National Science Council research project: “Evaluating Forged Coins Using Artificial Neural Networks” and “Identifying Images of Forged Coins Using Artificial Neural Networks”. This brought about a truly professional coin appraisal system, breaking through the longstanding monotonic method of relying solely on human experience, truly ushering in scientific technology for coin appraisal techniques.

In 2009, the related research paper on the subject of coin appraisal received high praise from international academic forums. A well-known American international scientific periodical (SCI): Machine Vision and Application, gave it especially high accolades. Furthermore, in 2010 the ACCA accepted an invitation from the National Central Mint to discuss and analyze forged coin identification techniques, where its identification technology received praise and approval from national and international circles. Then in 2012, the ACCA accepted an invitation from China’s Beijing Numismatic Museum to participate in an academic exchange of appraisal techniques with the Taiwan Coin & Paper Money Certification Society and the Taipei City Coin Collectors Association, further affirming its position as the truly professional third party coin appraisal agency.

Below is a bit of content excerpt from the research paper:
