#include <itkVideoFileReader.h>

Detailed Description

template<typename TOutputVideoStream>
class itk::VideoFileReader< TOutputVideoStream >

Reader that creates a VideoStream.

This class is responsible for reading video information from files. It is a subclass of VideoSource, giving it functionality to connect to other TemporalProcessObject classes (specifically, VideoToVideoFilter classes). It uses the temporal streaming implementation provided by TemporalProcessObject to load a single frame at a time into the frame buffer of the output VideoSource.
