Detailed Description

template<typename TInputVideoStream, typename TOutputVideoStream>
class itk::VideoToVideoFilter< TInputVideoStream, TOutputVideoStream >

Base class for filters that use a VideoStream as input and output.

VideoToVideoFilter is the base class for all process objects that output VideoStream data and requre VideoStream data as input. This class defines the SetInput() method for setting the input to a filter.

An implementation of GenerateInputRequestedRegion() is provided here that uses the implementation from TemporalProcessObject to generate input temporal regions and then provides its own mechanism for generating input spatial regions. The default implementation simply takes the requested spatial region from the first frame of output and uses that as the requested region for each of the input frames.
