Document scanning software needs to handle skewed, perspective-distorted pages captured from any angle — a problem that trips up many image-processing pipelines. This tutorial walks through a Java Swing desktop application that combines the LiteCam camera library with the Dynamsoft Capture Vision SDK (DDN) v3.4.1000 to detect document borders in...

Passport control kiosks, hotel check-in systems, and border verification software all rely on fast, accurate Machine-Readable Zone (MRZ) parsing from travel documents. Building that capability from scratch—reliable OCR, field validation, and live camera integration—is non-trivial. The Dynamsoft Capture Vision SDK exposes a single CaptureVisionRouter.capture() call that handles the full pipeline,...

When building Android applications that require barcode scanning capabilities, developers have several SDK options to consider. Two commonly used solutions are Google ML Kit Barcode Scanning and Dynamsoft Barcode Reader. ML Kit is a free, general-purpose machine learning SDK from Google, while Dynamsoft Barcode Reader is a commercial SDK specialized...

Machine Readable Zone (MRZ) recognition is a critical feature in applications that require scanning and processing identity documents, such as passports and visas. On Android devices, implementing accurate MRZ recognition can significantly enhance the efficiency and user experience of such apps. In this article, we will explore how to build...

Java Development Kit (JDK) does not provide a built-in API for camera access. A common workaround is to use OpenCV with Java bindings (such as JavaCV). However, OpenCV is a fairly large library, which may not be suitable for all applications. In this tutorial, we will demonstrate how to build...

Dynamsoft’s pre-built Android MRZ (Machine Readable Zone) Scanner component, which wraps low-level Dynamsoft Capture Vision API, is open-source and available for download on GitHub. An Android VIN (Vehicle Identification Number) Scanner has not been officially released yet, but a relevant example project is available. This article will guide you through...

VIN stands for vehicle identification number. It is a unique 17-character code to identify individual vehicles. The VIN contains information about your car’s make, model, and year, as well as the country where it was manufactured and other important details. You may find the VIN label on your car’s dashboard,...

In the previous article, we built a JavaFX demo app to scan documents using Dynamic Web TWAIN Service’s REST API. The demo app can scan documents via protocols like TWAIN, WIA, SANE, and ICA and save the documents into a PDF file using PDFBox. In this article, we are going...

Dynamic Web TWAIN is an SDK which enables document scanning from browsers. Under its hood, a backend service named Dynamic Web TWAIN Service is running to communicate with scanners via protocols like TWAIN, WIA, eSCL, SANE and ICA. The service runs on Windows, macOS and Linux. Starting from Dynamic Web...

Nowadays, web technologies have been used to create cross-platform apps. There are Capacitor for mobile development and Electron for desktop development. We can also use web technologies in existing apps. For example, the popular Java IDE, IntelliJ IDEA, uses JCEF (Java Chromium Embedded Framework) to create plugins. In this article,...
