Detailed Description

template<class TOutputVideoStream>
class itk::VideoSource< TOutputVideoStream >

A TemporalProcessObject that produces a VideoStream.

VideoSource acts as the base class for all TemporalProcess objects that produce a VideoStream as their output. This class defines GetOutput() which returns a pointer to the VideoStream object on output port 0.

The other roll that VideoSource plays is to implement the framework for spatial streaming to complement the temporal streaming implemented in TemporalProcessObject. This implementation mirrors the implementation in ImageSource except that each thread will be able to operate on a spatial region of each frame in the current temporal region that is being processed.
