The primary use of the function is in multi-camera environments, especially when the cameras do not

have hardware synchronization. That is, you call VideoCapture::grab() for each camera and after that

|
call the slower method VideoCapture::retrieve() to decode and get frame from each camera. This way

|
the overhead on demosaicing or motion jpeg decompression etc. is eliminated and the retrieved frames
|
|
from different cameras will be closer in time.
|
|
|
|
Also, when a connected camera is multi-head (for example, a stereo camera or a Kinect device), the
|
|
correct way of retrieving data from it is to call VideoCapture::grab first and then call
|
|
VideoCapture::retrieve one or more times with different values of the channel parameter. See
