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.

Method that gets called after all threads finish in TemporalStreamingGenerateData
Definition at line 156 of file itkVideoSource.h.
|
protectedvirtual |
The GenerateData method normally allocates the buffers for all of the outputs of a filter. Some filters may want to override this default behavior. For example, a filter may have multiple outputs with varying resolution. Or a filter may want to process data in place by grafting its input to its output.

Create an object from an instance, potentially deferring to a factory. This method allows you to create an instance of an object that is exactly the same type as the referring object. This is useful in cases where an object has been cast back to a base class.

Override GenerateOutputRequestedTemporalRegion to make sure that if the requested temporal region is not set, it gets set to the largest possible temporal region (using TemporalProcessObject's implementation) and the output has enough frame buffer slots to hold the entire request. We don't want the number of buffers to be changed for mid-pipeline filters since they will usually operate on fewer frames than requested at any given time. The solution is to only change the number of buffers if the requested temporal region was unset at the beginning of the call since mid-pipeline filters will always have their outputs' requested spatial regions set by the GenerateInputRequestedRegion call from the filter one further down the pipeline.

Make a DataObject of the correct type to used as the specified output. Every ProcessObject subclass must be able to create a DataObject that can be used as a specified output. This method is automatically called when DataObject::DisconnectPipeline() is called. DataObject::DisconnectPipeline, disconnects a data object from being an output of its current source. When the data object is disconnected, the ProcessObject needs to construct a replacement output data object so that the ProcessObject is in a valid state. So DataObject::DisconnectPipeline eventually calls ProcessObject::MakeOutput. Note that MakeOutput always returns a itkSmartPointer to a DataObject. ImageSource and MeshSource override this method to create the correct type of image and mesh respectively. If a filter has multiple outputs of different types, then that filter must provide an implementation of MakeOutput().

This method functions like SplitRequestedRegion in ImageSource and is used by the implementation of TemporalStreamingGenerateData to dispatch threads that call ThreadedGenerateData.
|
protectedvirtual |
We override the default implementation of TemporalStreamingGenerateData from TemporalProcessObject to provide functionality for spatial streaming. This implementation works exactly the same way as the implementation of GenerateData in ImageSource. The filter-specific implementation of ThreadedGenerateData will be responsible of accessing the correct frames.

ThreadedGenerateData here serves the same symnatic purpose as ThreadedGenerateData in ProcessObjects that handle Images. This is to say that ThreadedGenerateData is in charge of performing a single algorithmic operation on a portion of the requested region. The difference will come in the implementation of each filter. Subclass implementations must access the passed spatial region across the desired number of frames in the buffered TemporalRegion of the input.
WARNING: subclasses may need to handle the case where different frames have different spatial dimensions and thus some frames may not be accessible at the requested spatial region.
