In the present embodiment, at least one face amount identification subregion preset of bank note positive and negative is obtained respectively, particularly as follows: under default resolution, choose the characteristic area of bank note positive and negative as face amount identification subregion. Wherein, characteristic area is the region with face amount numeral or symbol. The face amount identification subregion preset includes the coordinate of subregion. Specifically, this default resolution is consistent with the banknote image resolution of the crawl of currency examination device, when using pixel as bank note transverse and longitudinal coordinate, if the resolution of banknote image is inconsistent, then the coordinate of the same position of same bank note can change. It is thus desirable to the banknote image resolution of the actual acquisition according to currency examination device, preset the face amount identification subregion at the numeral representing face amount on bank note or symbol place, and preset the coordinate of this face amount identification subregion.
In the present embodiment, for Iran's coin, the bank note face amount of 50,000,100,000 and 500,000 riyals is different, but bank note size is close. When resolution be 100DPI width is 100DPI, the reverse side at bank note selects first area as face amount identification subregion, selects second area and the 3rd region as face amount identification subregion in the front of bank note, wherein, the coordinate of first area is (5,60), (180,5); The coordinate of second area is (70,130), (100,10); The coordinate in the 3rd region is (50,10), (40,100). The numeral representing face amount it is respectively provided with, such that it is able to identify its face amount by the upper right comer region of its verso images in the upper right comer region of its verso images. Certainly other regions in front can also be selected on other currency type bank note, for instance dollar can select the region in the upper left corner or the upper right corner. And for the direct picture of 50,000,100,000 and 500,000 riyal bank note, it is inconsistent owing to representing the regional location of bank note face amount, and symbol is also different, 50,000 and 100,000 riyals are had to the Persian symbol representing face amount in its lower left corner, 500,000 its upper right corner tangible are provided with the digit symbol representing face amount.Therefore, for the face amount identification of Iran's coin direct picture, it is possible to select second area and the 3rd region to be jointly identified.
