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.
