Detailed Description

template<class TInputImage>
class itk::ContourExtractor2DImageFilter< TInputImage >

Computes a list of PolyLineParametricPath objects from the contours in a 2D image.

Uses the "marching squares" method to compute a the iso-valued contours of the input 2D image for a given intensity value. Multiple outputs may be produced because an image can have multiple contours at a given level, so it is advised to call GetNumberOfOutputs() and GetOutput(n) to retrieve all of the contours. The contour value to be extracted can be set with SetContourValue(). Image intensities will be linearly interpolated to provide sub-pixel resolution for the output contours.

The marching squares algorithm is a special case of the marching cubes algorithm (Lorensen, William and Harvey E. Cline. Marching Cubes: A High Resolution 3D Surface Construction Algorithm. Computer Graphics (SIGGRAPH 87 Proceedings) 21(4) July 1987, p. 163-170). A simple explanation is available here: http://www.essi.fr/~lingrand/MarchingCubes/algo.html

There is a single ambiguous case in the marching squares algorithm: if a given 2x2-pixel square has two high-valued and two low-valued pixels, each pair diagonally adjacent. (Where high- and low-valued is with respect to the contour value sought.) In this case, either the high-valued pixels can be connected into the same "object" (where groups of pixels encircled by a given contour are considered an object), or the low-valued pixels can be connected. This is the "face connected" versus "face + vertex connected" (or 4- versus 4-connected) distinction: high-valued pixels most be treated as one, and low-valued as the other. By default, high-valued pixels are treated as "face-connected" and low-valued pixels are treated as "face + vertex" connected. To reverse this, call VertexConnectHighPixelsOn();

Outputs are not guaranteed to be closed paths: contours which intersect the image edge will be left open. All other paths will be closed. (The closed-ness of a path can be tested by checking whether the beginning point is the same as the end point.)

Produced paths are oriented. Following the path from beginning to end, image intensity values lower than the contour value are to the left of the path and intensity values grater than the contour value are to the right. In other words, the image gradient at a path segment is (approximately) in the direct of that segment rotated right by 90 degrees, because the image intensity values increase from left-to-right across the segment. This means that the generated contours will circle clockwise around "hills" of above-contour-value intensity, and counter-clockwise around "depressions" of below-contour-value intensity. This convention can be reversed by calling ReverseContourOrientationOn().

By default the input image's largest possible region will be processed; call SetRequestedRegion() to process a different region, or ClearRequestedRegion() to revert to the default value. Note that the requested regions are usually set on the output; however since paths have no notion of a "region", this must be set at the filter level.

Allow people to add/remove/invoke observers (callbacks) to any ITK object. This is an implementation of the subject/observer design pattern. An observer is added by specifying an event to respond to and an itk::Command to execute. It returns an unsigned long tag which can be used later to remove the event or retrieve the command. The memory for the Command becomes the responsibility of this object, so don't pass the same instance of a command to two different objects

virtual void itk::ProcessObject::EnlargeOutputRequestedRegion ( DataObject * )

inlinevirtualinherited

Give the process object a chance to indictate that it will produce more output than it was requested to produce. For example, many imaging filters must compute the entire output at once or can only produce output in complete slices. Such filters cannot handle smaller requested regions. These filters must provide an implementation of this method, setting the output requested region to the size they will produce. By default, a process object does not modify the size of the output requested region.

void itk::ProcessObject::GenerateOutputInformation ( void )

protectedvirtualinherited

Generate the information decribing the output data. The default implementation of this method will copy information from the input to the output. A filter may override this method if its output will have different information than its input. For instance, a filter that shrinks an image will need to provide an implementation for this method that changes the spacing of the pixels. Such filters should call their superclass' implementation of this method prior to changing the information values they need (i.e. GenerateOutputInformation() should call Superclass::GenerateOutputInformation() prior to changing the information.

void itk::ProcessObject::GenerateOutputRequestedRegion ( DataObject * output )

protectedvirtualinherited

Given one output whose requested region has been set, how should the requested regions for the remaining outputs of the process object be set? By default, all the outputs are set to the same requested region. If a filter needs to produce different requested regions for each output, for instance an image processing filter producing several outputs at different resolutions, then that filter may override this method and set the requested regions appropriatedly.

Note that a filter producing multiple outputs of different types is required to override this method. The default implementation can only correctly handle multiple outputs of the same type.

By default we set all the output requested regions to be the same.

OutputPathType* itk::PathSource< PolyLineParametricPath< 2 > >::GetOutput ( void )

inherited

Get the output data of this process object. The output of this function is not valid until an appropriate Update() method has been called, either explicitly or implicitly. Both the filter itself and the data object have Update() methods, and both methods update the data. Here are three ways to use GetOutput() and make sure the data is valid. In these examples, image is a pointer to some Image object, and the particular ProcessObjects involved are filters. The same examples apply to non-image (e.g. Mesh) data as well.

anotherFilter->SetInput( someFilter->GetOutput() );

anotherFilter->Update();

In this situation, someFilter and anotherFilter are said to constitute a pipeline.

image = someFilter->GetOutput();

image->Update();

someFilter->Update();

image = someFilter->GetOutput();

(In the above example, the two lines of code can be in either order.)

Note that Update() is not called automatically except within a pipeline as in the first example. When streaming (using a StreamingImageFilter) is activated, it may be more efficient to use a pipeline than to call Update() once for each filter in turn.

For an image, the data generated is for the requested Region, which can be set using ImageBase::SetRequestedRegion(). By default, the largest possible region is requested.

virtual void itk::PathSource< PolyLineParametricPath< 2 > >::GraftNthOutput	(	unsigned int	idx,
		OutputPathType *	output
	)

virtualinherited

Graft the specified data object onto this ProcessObject's idx'th output. This is the similar to GraftOutput method except is allows you specify which output is affected. The specified index must be a valid output number (less than ProcessObject::GetNumberOfOutputs()). See the GraftOutput for general usage information.

virtual void itk::PathSource< PolyLineParametricPath< 2 > >::GraftOutput ( OutputPathType * output )

virtualinherited

Graft the specified DataObject onto this ProcessObject's output. This method grabs a handle to the specified DataObject's path data to use as its output's own path data. It also copies the region ivars (RequestedRegion, BufferedRegion, LargestPossibleRegion) and meta-data (Spacing, Origin) from the specified data object into this filter's output data object. Most importantly, however, it leaves the Source ivar untouched so the original pipeline routing is intact. This method is used when a process object is implemented using a mini-pipeline which is defined in its GenerateData() method. The usage is:

        // setup the mini-pipeline to process the input to this filter
        firstFilterInMiniPipeline->SetInput( this->GetInput() );
    
        // setup the mini-pipeline to calculate the correct regions
        // and write to the appropriate bulk data block
        lastFilterInMiniPipeline->GraftOutput( this->GetOutput() );
    
        // execute the mini-pipeline
        lastFilterInMiniPipeline->Update();
    
        // graft the mini-pipeline output back onto this filter's output.
        // this is needed to get the appropriate regions passed back.
        this->GraftOutput( lastFilterInMiniPipeline->GetOutput() );

For proper pipeline execution, a filter using a mini-pipeline must implement the GeneratseInputRequestedRegion(), GenerateOutputRequestedRegion(), GenerateOutputInformation() and EnlargeOutputRequestedRegion() methods as necessary to reflect how the mini-pipeline will execute (in other words, the outer filter's pipeline mechanism must be consistent with what the mini-pipeline will do).

virtual DataObjectPointer itk::PathSource< PolyLineParametricPath< 2 > >::MakeOutput ( unsigned int idx )

virtualinherited

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 SmartPointer to a DataObject. If a subclass of ImageSource has multiple outputs of different types, then that class must provide an implementation of MakeOutput().

virtualinherited

Send the requested region information back up the pipeline (to the filters that preceed this one).

 check flag to avoid executing forever if there is a loop

 Give the subclass a chance to indicate that it will provide
 more data then required for the output. This can happen, for
 example, when a source can only produce the whole output.
 Although this is being called for a specific output, the source
 may need to enlarge all outputs.

 Give the subclass a chance to define how to set the requested
 regions for each of its outputs, given this output's requested
 region.  The default implementation is to make all the output
 requested regions the same.  A subclass may need to override this
 method if each output is a different resolution.

 Give the subclass a chance to request a larger requested region on 
 the inputs. This is necessary when, for example, a filter
 requires more data at the "internal" boundaries to 
 produce the boundary values - such as an image filter that
 derives a new pixel value by applying some operation to a 
 neighborhood of surrounding original values.

 Now that we know the input requested region, propagate this
 through all the inputs.

A filter may need to release its input's bulk data after it has finished calculating a new output. The filter may need to release the inputs because the user has turned on the ReleaseDataFlag or it may need to release the inputs because the filter is an "in place" filter and it has overwritten its input with its output data. The implementation here simply checks the ReleaseDataFlag of the inputs. InPlaceImageFilter overrides this method so release the input it has overwritten.

virtual void itk::ProcessObject::SetReleaseDataBeforeUpdateFlag ( bool _arg )

virtualinherited

Turn on/off the flags to control whether the bulk data belonging to the outputs of this ProcessObject are released/reallocated during an Update(). In limited memory scenarios, a user may want to force the elements of a pipeline to release any bulk data that is going to be regenerated anyway during an Update() in order to control peak memory allocation. Note that this flag is different from the ReleaseDataFlag. ReleaseDataFlag manages the deallocation of a ProcessObject's bulk output data once that data has been consumed by a downstream ProcessObject. The ReleaseDataBeforeUpdateFlag manages the deallocation/reallocation of bulk data during a pipeline update to control peak memory utilization. Default value is on.

void itk::ProcessObject::SetReleaseDataFlag ( bool flag )

virtualinherited

Turn on/off the flags to control whether the bulk data belonging to the outputs of this ProcessObject are released after being used by a downstream ProcessObject. Default value is off. Another options for controlling memory utilization is the ReleaseDataBeforeUpdateFlag.

void itk::ProcessObject::Update ( void )

virtualinherited

Bring this filter up-to-date. Update() checks modified times against last execution times, and re-executes objects if necessary. A side effect of this method is that the whole pipeline may execute in order to bring this filter up-to-date. This method updates the currently prescribed requested region. If no requested region has been set on the output, then the requested region will be set to the largest possible region. Once the requested region is set, Update() will make sure the specified requested region is up-to-date. This is a confusing side effect to users who are just calling Update() on a filter. A first call to Update() will cause the largest possible region to be updated. A second call to Update() will update that same region. If a modification to the upstream pipeline cause a filter to have a different largest possible region, this second call to Update() will not cause the output requested region to be reset to the new largest possible region. Instead, the output requested region will be the same as the last time Update() was called. To have a filter always to produce its largest possible region, users should call UpdateLargestPossibleRegion() instead.

The following methods are used to coordinate the execution of the data processing pipeline.

void itk::ProcessObject::UpdateLargestPossibleRegion ( )

virtualinherited

Like Update(), but sets the output requested region to the largest possible region for the output. This is the method users should call if they want the entire dataset to be processed. If a user wants to update the same output region as a previous call to Update() or a previous call to UpdateLargestPossibleRegion(), then they should call the method Update().

Definition at line 1120 of file itkProcessObject.cxx.

void itk::ProcessObject::UpdateOutputData ( DataObject * output )

virtualinherited

Actually generate new output

 prevent chasing our tail

 Prepare all the outputs. This may deallocate previous bulk data.

 Propagate the update call - make sure everything we
 might rely on is up-to-date
 Must call PropagateRequestedRegion before UpdateOutputData if multiple 
 inputs since they may lead back to the same data object.

 Cache the state of any ReleaseDataFlag's on the inputs. While the
 filter is executing, we need to set the ReleaseDataFlag's on the
 inputs to false in case the current filter is implemented using a
 mini-pipeline (which will try to release the inputs).  After the
 filter finishes, we restore the state of the ReleaseDataFlag's
 before the call to ReleaseInputs().

 Tell all Observers that the filter is starting

 GenerateData this object - we have not aborted yet, and our progress
 before we start to execute is 0.0.

 Count the number of required inputs which have been assigned

 If we ended due to aborting, push the progress up to 1.0 (since
 it probably didn't end there)

 Notify end event observers

 Now we have to mark the data as up to date.

 Restore the state of any input ReleaseDataFlags

 Release any inputs if marked for release

void itk::ProcessObject::UpdateOutputInformation ( void )

virtualinherited

Update the information decribing the output data. This method transverses up the pipeline gathering modified time information. On the way back down the pipeline, this method calls GenerateOutputInformation() to set any necessary information about the output data objects. For instance, a filter that shrinks an image will need to provide an implementation for GenerateOutputInformation() that changes the spacing of the pixels. Such filters should call their superclass' implementation of GenerateOutputInformation prior to changing the information values they need (i.e. GenerateOutputInformation() should call Superclass::GenerateOutputInformation() prior to changing the information.

 Watch out for loops in the pipeline

   Since we are in a loop, we will want to update. But if
   we don't modify this filter, then we will not execute
   because our OutputInformationMTime will be more recent than
   the MTime of our output.

 We now wish to set the PipelineMTime of each output DataObject to
 the largest of this ProcessObject's MTime, all input DataObject's
 PipelineMTime, and all input's MTime.  We begin with the MTime of
 this ProcessObject.

 Loop through the inputs

     Propagate the UpdateOutputInformation call

     What is the PipelineMTime of this input? Compare this against
     our current computation to find the largest one.

     Pipeline MTime of the input does not include the MTime of the 
     data object itself. Factor these mtimes into the next PipelineMTime

 Call GenerateOutputInformation for subclass specific information.
 Since UpdateOutputInformation propagates all the way up the pipeline,
 we need to be careful here to call GenerateOutputInformation only if
 necessary. Otherwise, we may cause this source to be modified which
 will cause it to execute again on the next update.

   Keep track of the last time GenerateOutputInformation() was called
