OpenCV Video Capture
openCV Library The open source computer vision li-brary OpenCV began as a research project at Intel in 1998 5 It has been available since 2000 under the BSD open source license OpenCV is aimed at providing the tools needed to solve computer-vision problems It contains a mix of low-level image-processing functions and high-level algorithms
Object Tracking Using OpenCV - Clemson University
OpenCV package has a function selectROI through which we can select one or multiple objects in one frame of a video Then we create a tracker to track the selected area (a rectangle can be or not an object) The tracker continues to track the selected object and updates frame by frame Compared with object detection tracking runs faster can

How does OpenCV work with a camera?
- OpenCV provides the VideoCature () function which is used to work with the Camera. We can do the following task: Read video, display video, and save video. Capture from the camera and display it. OpenCV allows a straightforward interface to capture live stream with the camera (webcam). It converts video into grayscale and display it.
How do I choose the best OpenCV package?
- OpenCV 3 or higher is recommended for this book's purposes. Also, check whether the packages offer Python bindings and depth camera support via OpenNI and SensorKinect. Finally, check whether anyone in the developer community has reported success or failure in using the packages.
What is project cameo in OpenCV?
- Project Cameo (fface tracking and image manipulation) OpenCV is often studied through a cookbook approach that covers a lot of algorithms but nothing about high-level application development. To an extent, this approach is understandable because OpenCV's potential applications are so diverse.
