This article will help developers who prefer to use Java and OPENCV environments. This program is made entirely of NetBeans 6.9.1. This application shows how to use OPENCV in a NetBeans environment. In this case, the concept of multithreading is used to capture video from webcam or video files. This example shows a complete illustration of how to create a program using NetBeans. In this article, I have revealed how to configure NetBeans to perform OPE

For a long time, the capture of audio and video information has been a difficult point in web development. For many years, we have relied on browser plugins to implement this requirement.In HTML 5, there are many APIs that can access hardware devices, such as the Geolocation API to access the GPS device, the orientation API to access the accelerometer device, the WebGL API to access the GPU device, Access the audio playback device's web Voice API and more. These APIs are very powerful, because d
