Beschreibung: 本人在指导老师的指导下，以EAN13格式的条码图像为例，进行了条码图像识别算法的研究工作，主要的研究目的就是通过利用各种数字图像处理技术，对图像中的条码部分进行特征提取、分析，快速、准确、高效地识别出图像中的条码内容。在指导老师的指导下，本人经过不断的探索研究，最终完成了对条码图像的识别工作，并将条码图像识别过程分解为以下三个步骤： 1) 图像预处理：通过合适的灰度化和二值化处理算法，将条码图像的真彩图像转换为黑白二值图像，从而将条码的条空区域的特征表现出来，将条码的条空与图像中其他内容区分开。 2) 条码区域定位：通过寻找条码区域条空变化次数的特征，来找到条码区域，确定包含完整条码的矩形. ; This thesis is a research about the image recognition algorithms for bar code images, especially those in EAN13 formats. The objective of this thesis is to efficiently recognize the bar code content in given images using image processing technologies. In this thesis, the recognition for bar code images is fulfilled in the following three steps. The first step is to preprocess the images.
