基于纸币退化能量函数的清分机纸币新旧和残缺检测方法
摘要：
本发明提供一种基于纸币退化能量函数的清分机纸币新旧残缺检测方法。本发明的目的是这样实现的：首先建立参考图像模板，接着对纸币图像进行配准，在图像配准过程中，利用几何特征进行全局配准，利用颜色扩散模型进行局部配准，最后根据配准结果检测残缺及新旧特征，并依据BDE函数对纸币新旧和残缺作出评估。步骤包括：参考图像模板的设立；图像的全局配准；图像局部配准；根据BDE函数对纸币新旧和残缺作出评估。本发明一种基于纸币退化能量函数的清分机纸币新旧残缺检测方法，具有识别率高且稳定可靠的优点，能满足实际要求，并已应用到实际的纸币清分系统中。
摘要（英）：

The invention provides a method for detecting old and new as well as deformity of paper currency by a sorting machine based on a paper currency degeneration energy function. The aim of the method provided by the invention is realized through the following steps: firstly establishing a reference image template; then registering paper currency images; carrying out global registration by utilizing geometrical characteristics in the process of image registration; carrying out partial registration by utilizing a color diffusion model; and detecting the deformity as well as old and new characteristics according to the registration result, and estimating the old and new as well as deformity of the paper currency according to a BDE (basic data exchange) function. The method provided by the invention comprises the following steps: establishment of the reference image template, global registration of images, partial registration of images, and estimation on the old and new as well as deformity of the paper currency according to the BDE function. The method for detecting the old and new as well as deformity of the paper currency by the sorting machine based on the paper currency degeneration energy function has the advantages of high recognition rate, stability and reliability; and the method provided by the invention can meet practical requirements and is applied to a practical paper currency sorting system.
