Image annotation is a key step in deep learning. It prepares the data for tasks like image classification, object detection, semantic segmentation, etc.

When using a Barcode reader or scanner SDK, we primarily focus on the detection speed and recognition accuracy. There are many factors that may affect the performance of the Barcode detection SDK. The factors can be approximately classified into two categories: image quality ...

QR Code is widely used in our everyday life. As a two-dimensional barcode, it can store more data than 1D barcodes. It can be captured using a camera and then be decoded using image processing methods.

Motion detection can detect whether there is a change in the positions of objects. It can be achieved by many methods. For example, infrared light or laser technology can be used for optical detection. As for image processing methods, there is a basic one by a fixed camera, w ...

Dynamsoft Camera Enhancer (DCE) provides high-level APIs for developers to quickly create a camera application, such as a barcode scanner and a text scanner.

The Flutter barcode SDK series is coming to the end. This week, we switch the coding environment to macOS to finish the rest of the plugin platforms - iOS and macOS - using Swift.

In the B4X developing suite, B4J is used to develop desktop apps based on JavaFX or server apps based on Jetty. By default, it cannot be used to create web applications without a server. A third-party library, BANano, makes this possible. It can transpile everything you write ...

In the previous article, we created a Dynamsoft Barcode Reader library for B4X. Here, we are gonna use the library to create a barcode scanner which reads barcodes from the camera stream.

For the past several weeks, the Flutter plugin of Dynamsoft Barcode Reader has covered Windows, Android and Web. This week, we go through the plugin implementation for Linux. Similar to Windows, we combine Dart and C++ code for Linux. The unexpected thing is the C++ data type ...

B4X is a set of rapid development tools which can be used to develop apps for all the major mobile and desktop platforms.

Have you had such an experience that you need to scan a QR code displayed on a screen in the front of a meeting room but you sat in the back? You opened the barcode scanning app and aimed it at the code, but it just couldn’t read the code. Of course, it is better to make the ...

This week, I made a new attempt, integrating Dynamsoft JavaScript Barcode SDK into the ongoing Flutter barcode plugin project. It is exciting to be capable of building web barcode reader apps with the same decodeFile() method used for mobile and desktop development.

About two years ago, I wrote an article sharing how to build a Flutter barcode plugin with Dynamsoft Barcode Reader step by step. At that time, Flutter was still under development and only supported Android and iOS. Nowadays, Google has released Flutter 2, which allows develo ...

Camera control and barcode reading are two essential parts of a barcode scanner.

QR code can store much more data than 1D code. But do you know how much data it can represent?

Originally designed for the automotive industry1, QR code (abbreviated from Quick Response code) has become popular in various usage scenarios. QR codes can encode richer content than 1D barcodes, from website URLs to even a small image. They can be displayed on screens and p ...

Apple announced new Mac models with Apple M1 chip recently. Although Dynamsoft has not released an Apple Silicon version of Dynamsoft Barcode Reader SDK yet, I am curious how will x86_64 barcode SDK perform under Rosetta 2. In this article, I will build a simple command-line ...

In my previous article, I shared how to integrate Dynamsoft Barcode Reader to LabelImg for annotating barcode objects. It is time to take a further step to make some custom models for barcodes. In this article, I will go through the process that I used Darknet to train YOLO v ...

ZXing is an open-source, 1D/2D barcode image processing library implemented in Java. The supported barcode formats include UPC-A, UPC-E, EAN-8, Code 93, Code 128, QR Code, Data Matrix, Aztec, PDF 417, etc. Besides the Java version, developers can leverage other ported project ...

Recently, I found an excellent jQuery plugin jquery.qrcode.js, which is written by Jerome Etienne. In this article, I would like to share how to use the QR code plugin to implement a free online app with Google App Engine. You can try my demo http://dynamsoft-test.appspot.com/.

Barcode scanning, especially QR code scans, are now widely used in various applications. This includes advertisements, newspapers, social networks, signage, and so on. The growth of QR codes is in large part due to the smartphone market’s booming growth. As a result, scanning ...
