| 摘 要： | 由于受到条码采集设备的限制，图像中经常混有很多噪声，导致出现误码．引入了基于偏微分方程（PDE）的Perona—Malik模型，并对Perona-Malik模型的缺点进行了算法改进，给出了一种针对条码图像去噪的方法．通过合理地设计和选择参数，得到了比较令人满意的结果．

| Abstract: | At present, the 1-D bar codes were used widly in many aspects, but due to the acquiring equipment which results in noisy images, some mistakes appear. This paper introduced PDE-based Perona-Malik model and a method was improved to apply to 1-D bar code images. According to different parameters given,its results were encouraging. |
