Description: 介绍一种实用的二维条码识别算法。首先探讨了二维条码的定位与分割算法,利用Hough变换与Sobel边缘检测把条码图像从原始采集的图像中有效地分割出来 然后分析了条码图像经过光学系统的噪声模型,提出了一种计算点扩展函数标准方差的算法 采用Flourier变换自适应地选取阈值去除噪声导致的无效边界,从而得到条码的基本模块。实验结果表明,该算法具有很好的抗噪性,提高了二维条码的识别率。
-A practical two-dimensional barcode recognition algorithms. First of all two-dimensional bar code of the positioning and segmentation algorithm using Hough Transform and Sobel edge detection of the bar code images collected from the original image to effectively separate and then analyzes the barcode image through the optical system of the noise model, put forward a Calculation of point spread function of standard deviation of the algorithm uses Flourier transform adaptively select the threshold to remove noise caused by invalid border, bar code and thus be the basic module. Experimental results show that the algorithm has good noise immunity, improved two-dimensional bar code recognition rate. Platform: |

Description: QRCode decoder SDK是一个强大，高效率和快速搜索, 检测, 定位QRCode 条码的图像扫描开发工具包。QRCode条形码可以在一个小图像上储存大量的数据，最大可达到7089位数字，4296个字母，2953二进制数据，1817日文字符。而一维条码通常用于存储一个记录或帐号，然后必须从数据库中检索，以便获得额外的信息。 QRCode条码通常可以存储所有信息或一个特定的记录。利用QRCode条形码，开发者可以不必进行数据库信息检索就可以直接从识别得到的数据中得到所有详细资料。
使用此开发库，开发者可以阅读倾斜或翻转的条码。识别库的输入可以是各种图片格式，如JPG，PNG，BMP，GIF等， 也可以是从照相机或摄像机中得到的图像帧
-Decoder SDK QRCode is a powerful, efficient and fast search, detection, and positioning QRCode barcode image scan development kit. QRCode bar code can be stored in a small image of a large number of data, the maximum can reach 7089 digits, 4296 letters, 2953 binary data, 1817 Japanese characters. And one dimensional bar code is usually used to store a record or account, and then must be retrieved the in order to obtain additional information. QRCode bar code can usually store all the information or a specific record. Using QRCode bar code, the developer can not have to carry out the information retri can directly the identification of the data obtained in all the details.
Using this development library, developers can read the tilt or flip of the bar code. The input can be a variety of image formats, such as JPG, PNG, BMP, GIF, etc., can also be obtained the camera or the camera image frame
