基于一维傅里叶变换特征提取的纸币识别

纸币识别系统包括纸币图像采集、图像预处理、特征提取及分类器设计等几个步骤。其中特征提取的有效性直接影响到整个系统的识别效果,是至关重要的环节。本文针对不同面值长宽、图案相近的纸币,提出一种局部区域一维傅里叶变换特征提取的新方法。实验结果表明,该方法取得了很高的识别率,有较大的实际应用价值。

Paper Currency Recognition Based on Feature Extraction of One Dimension Fourier Transform

A system of paper currency recognition includes image collection,preprocessing,feature extraction and classifier design.A critical step is the feature extraction which directly influences the recognition effect of the whole system.Especially to recognize paper currency which are different in par value but similar in length,width and pattern,a new feature extraction method is proposed,which is based on one dimension Fourier transform in part area.The experiment result shows that this method leads to a high r...
