二维码机器学习：开发人员教程

发布 2023年八月29日

快速反应(QR)代码已成为现代社会不可或缺的一部分，彻底改变了信息共享和访问的方式。这些二维 BarCode 由黑白方块矩阵组成，使用智能手机摄像头扫描即可快速检索存储的信息，如 URL、联系方式、网站 URL、产品详细信息等。然而，随着技术的发展，二维码的功能也在不断提升。机器学习(ML)在增强 QR 代码生成、识别和解码过程中，《QR.NET》已成为一种强大的工具，可带来更好的用户体验和更强大的功能。

二维码和 BarCode 的广泛使用改变了信息和数据交换的世界。这些二维码可以快速访问数字内容，在各行各业发挥着不同的作用。然而，区分 QR 码和 BarCode 可能具有挑战性，尤其是在处理各种不同的代码时。利用机器学习的强大功能(ML)通过.NET/C# Framework，开发人员可以创建一个智能系统，对 QR 码和 BarCode 进行准确分类，从而简化数据处理并增强用户体验。集成 IronBarcode 的解码功能进一步增强了该解决方案，可从识别的代码中准确提取内容。

在本文中，我们将对模型进行训练，该模型将把给定的输入内容分类为 BarCode 或 QR Code，之后，我们将使用 IronBarcode 对输入代码进行解码。
