Description

ここで、１つのＬＵＴ５によってサンプル画像２の画素のアドレスを指定するときに、本来指定すべき位置の画素に対して上下左右方向の数画素の範囲内で１画素ずつずらして指定するようにする。例えば本来指定すべき位置の画素に対して上下左右方向に５画素ずれた範囲内で指定する場合は、本来の画素の座標を（０，０）とすると、（−５，＋５）〜（＋５，−５）の範囲内の全ての座標について計１２１回の相関演算を行うようにする。そして、この相関演算の中で最も類似度が高い値を採用する。これにより、認識すべき画像の位置ずれ等による認識精度の低下を抑えることができる。特に、有価証券の端部の検出精度が低い場合の認識精度を向上することができる。 Here, when the address of the pixel of the sample image 2 is specified by one LUT 5, the pixel at the position where it should be originally specified is specified by shifting it by one pixel within the range of several pixels in the vertical and horizontal directions. .. For example, when specifying within a range of 5 pixels offset in the vertical and horizontal directions with respect to the pixel at the position that should be originally specified, assuming that the coordinates of the original pixel are (0,0), (-5, + 5) to (+5) , -5), the correlation calculation is performed 121 times in total for all the coordinates. Then, the value having the highest degree of similarity in this correlation calculation is adopted. As a result, it is possible to suppress a decrease in recognition accuracy due to misalignment of the image to be recognized. In particular, it is possible to improve the recognition accuracy when the detection accuracy of the end of the securities is low.
