| 摘 要： | 复杂背景下的二维条码区域提取一直是Data Matrix条码解码过程中的难题之一.通过对图像进行形态学分析从而确定条码的可能区域的方法因计算简单而被广泛应用,但存在着形态学结构体难以选择和虚警率比较高的缺点.为克服这些缺点,提出了基于Gabor滤波和BP神经网络的Data Matrix条码区域提取方法(GF-BPNN).用不同尺度不同方向的Gabor滤波器对图像进行滤波提取其纹理特征,再进行特征变换,使所得特征具有尺度和旋转不变性;然后利用BP神经网络按照前述特征对像素进行分类,再经过形态学后处理提取条码区域.实验结果表明,与进行形态学分析的方法相比,GF-BPNN具有较高的准确率和鲁棒性.

| Abstract: | Extracting 2D barcode region in complex backgrounds has always been a key problem in the procedure of Data Matrix barcode decoding. Thanks to its low computation complexity,morphological analysis was widely applied in extracting potential regions of Data Matrix barcodes,with inherent defects of high false accept rate and difficulty in choosing appropriate structuring element though. In order to overcome these drawbacks,the method of Data Matrix barcode region extraction,based on Gabor filtering and BP neura... |
