摘要
针对高仿真纸币识别问题,提出了采用三维线性插值法实现纸币图案RGB色彩空间向Lab标准色彩空间转换,解决纸币色彩R、G、B值因扫描和显示装置不同而出现的差异,提高了纸币识别方法的通用性;提出了通过提取纸币某一特征色块的R、G、B值,进行色彩空间转换,matlab编程求得真假纸币特征色块R、G、B值对应的l、a、b值和色差。结果表明,以三维线性插值法为模型进行色彩空间转换,用色差的方法来识别纸币真伪是可行的,纸币识别正确率达100%。
Aiming at the identification problem of high simulation notes, this paper proposed the three dimensional linear interpolation method to achieve the paper pattern space conversion from RGB color space to standard Lab color space, which can solve the paper color R、G and B value differences that caused by different scanning and displaying equipment. This method can improve the versatility of paper identification. By extracting features of color piece of R、G、B value and color space conversion,after the processing of matlab, can obtain the true and false banknotes l, a and b value and color difference corresponding to R, G and B;The results shows that by using three dimensional linear interpolation method for the model and conducting color space conversion,this color difference method can identify the paper feasibly, which can up to 100% of paper currency recognition.
