          org.opencv.android.NativeCameraView

public class NativeCameraView
extends CameraBridgeViewBase

This class is an implementation of a bridge between SurfaceView and native OpenCV camera. Due to the big amount of work done, by the base class this child is only responsible for creating camera, destroying camera and delivering frames while camera is enabled

connectCamera in class CameraBridgeViewBase

Parameters:

width - - the width of this SurfaceView

height - - the height of this SurfaceView

disconnectCamera

protected void disconnectCamera()

Description copied from class: CameraBridgeViewBase

Disconnects and release the particular camera object being connected to this surface view. Called when syncObject lock is held
