Combination of spatially enhanced bag-of-visual-words model and genuine difference subspace for fake coin detection

作者：

Highlights：

• An intelligent system is proposed to detect fake coins automatically.

• The spatially enhanced bag-of-visual-words model excels at representing coins.

• The coin representation is improved by building a genuine difference subspace.

• A classifier using subspace representations is effective for fake coin detection.

• Promising experimental results in excess of 98
