According to the statistics of Stack Overflow traffic, Python is the fastest-growing major programming language in high-income countries. Python seems to be promising in the future. I have noticed that many of the developers who would like to use Dynamsoft Barcode Reader SDK for Linux are more interested in Python rather than C/C++ or Java. In this post, I will illustrate how to build the Python barcode extension with DBR 5.2.
From version 4.x to 5.x, Dynamsoft improved Barcode SDK performance with a big leap. Unfortunately, only Windows edition is available for download so far. In this post, I will share how to create a Node.js extension with the preview version of Dynamsoft Linux Barcode SDK 5.2. If you are interested in Windows edition, please read – Building Node.js Barcode Addon with DBR v5.0.
Many excellent document mobile apps support not only image capture, but also edge detection and perspective transformation. If you are interested in these computer vision technologies, you can use OpenCV to create a free document scanner app yourself. In this post, I want to share how to use OpenCV-Python to create a web document scanner step by step.
Recently, I was inspired by a blog post “Python Live Video Streaming Example” and thinking whether it is possible to save the camera streaming to a video file. Based on the example code, I managed to figure out a solution. In this post, I want to share the process of building the web camera recorder using OpenCV and Flask.
Using OpenCV APIs to capture video from a camera is convenient. However, OpenCV does not provide an API for listing all available devices. If you have multiple cameras connected to your PC, you have no idea how to choose the right one. To get device information on Windows, you need to invoke DirectShow APIs. In this post, I will share how to create a Python extension that lists camera devices for OpenCV-Python on Windows.
Dynamic Web TWAIN has been widely used for developing web browser based document scanning apps. Is it possible to embed Dynamic Web TWAIN APIs into a Chrome app or extension? In this post, I want to share what I went through while building a Chrome extension.
This article is about how to use OpenCV and Dynamsoft Barcode Reader SDK to create a Python barcode reader on macOS.
Chrome OS, developed by Google, is a light-weighted operating system based on the Linux kernel. It uses Chrome web browser as the user interface that primarily supports web applications released as Chrome extensions. However, Chrome extension is not fresh to me. When running Chrome OS in a virtual machine, I wondered whether it is possible to run native apps. In this article, I want to share how to run a console application built with Dynamsoft C/C++ Barcode SDK on Chrome OS.
