#include <itkOpenCVVideoCapture.h>
This class implements OpenCV's VideoCapture API and takes an itk VideoStream as input.
This implementation of cv::VideoCapture provides the additional method open( itk::VideoStream* ) to "open" video data from an ITK pipeline. The traditional open methods will throw exceptions, so it can only be used to access the output of an ITK video pipeline from an OpenCV capture context.

Constructor that initializes internal VideoStream to null

Constructor that takes a VideoStream as input
|
inlinevirtual |
Destructor that does nothing. The VideoStream will be freed by the source that generated it.

virtual |
Add an open method that takes a TemporalDataObject. This checks to make sure that it can be cast to a VideoStream
|
virtual |
Stream the next frame into the provided image. Equivalent to grab() + retrieve(image, 0)
|
virtual |
non-operator version of >>'s functionality
|
virtual |
Just set the internal pointer to null. Let the upstream filters take care of actually freeing the memory
|
virtual |
Access the current frame of the VideoStream
