快速回應碼（QR碼）已成為現代社會不可或缺的一部分，徹底改變了資訊的共享和獲取方式。這些二維條碼由黑白方塊矩陣組成，可以使用智慧型手機相機掃描，快速檢索儲存的信息，例如網址、聯絡資訊、網站網址、產品詳情等。然而，隨著技術的發展，二維碼的功能也不斷發展。機器學習 (ML) 已成為增強二維碼生成、識別和解碼流程的強大工具，從而改善使用者體驗並提高功能。

二維碼和條碼的廣泛應用徹底改變了資訊和資料交換的世界。這些二維條碼可以快速存取數位內容，並在各行各業中發揮各種作用。然而，區分二維碼和條碼可能很困難，尤其是在處理各種各樣的程式碼時。借助機器學習 (ML) 和 .NET/C# 框架，開發人員可以創建一個智慧型系統，準確地對二維碼和條碼進行分類，從而簡化資料處理並增強使用者體驗。整合 IronBarcode 的解碼功能進一步增強了解決方案，能夠從識別出的條碼中準確提取內容。

在本文中，我們將訓練一個模型，該模型可以將給定的輸入分類為條碼或二維碼，之後，我們將使用 IronBarcode 對輸入代碼進行解碼。
