OpenCV officially provides both C++ and Python APIs for developers. Most of the time, developers just need to use one kind of programming languages to read, write and process images with hundreds of computer vision algorithms. However, if you want to use OpenCV Python APIs with an extended C/C++ library,...

If you have a USB camera, how can you build a simple C# camera application on Windows 10? There are three options:  WIA (Windows Imaging Acquisition), DirectShow and MediaCapture. After trying some sample code that downloaded from CodeProject and GitHub, I got the conclusion: 1. WIA is not good because...

In this tutorial, I want to make a more complicated WebSocket demo, which enables me to capture images from scanners on server side, and view the images in desktop web browsers or mobile web browsers.
