Detailed Description

template<typename TInputImage, typename TOutputImage, typename TDistancePixel = float>
class itk::SLICImageFilter< TInputImage, TOutputImage, TDistancePixel >

Simple Linear Iterative Clustering (SLIC) super-pixel segmentation.

The Simple Linear Iterative Clustering (SLIC) algorithm groups pixels into a set of labeled regions or super-pixels. Super-pixels follow natural image boundaries, are compact, and are nearly uniform regions which can be used as a larger primitive for more efficient computation. The SLIC algorithm can be viewed as a spatially constrained iterative k-means method.

The original algorithm was designed to cluster on the joint domain of the images index space and it's CIELAB color space. This implementation works with images of arbitrary dimension as well as scalar, single channel, images and most multi-component image types including ITK's arbitrary length VectorImage.

The distance between a pixel and a cluster is the sum of squares of the difference between their joint range and domains ( index and value ). The computation is done in index space with scales provided by the SpatialProximityWeight parameters.

The output is a label image with each label representing a superpixel cluster. Every pixel in the output is labeled, and the starting label id is zero.

This code was contributed in the Insight Journal paper: "Scalable Simple Linear Iterative Clustering (SSLIC) Using a Generic and Parallel Approach" by Lowekamp B. C., Chen D. T., Yaniv Z., Yoo T. S. https://hdl.handle.net/1926/3596

If an imaging filter needs to perform processing after all processing threads have completed, the filter can can provide an implementation for AfterThreadedGenerateData(). The execution flow in the default GenerateData() method will be: 1) Allocate the output buffer 2) Call BeforeThreadedGenerateData() 3) Spawn threads, calling ThreadedGenerateData() in each thread. 4) Call AfterThreadedGenerateData() Note that this flow of control is only available if a filter provides a ThreadedGenerateData() method and NOT a GenerateData() method.

If an imaging filter needs to perform processing after the buffer has been allocated but before threads are spawned, the filter can can provide an implementation for BeforeThreadedGenerateData(). The execution flow in the default GenerateData() method will be: 1) Allocate the output buffer 2) Call BeforeThreadedGenerateData() 3) Spawn threads, calling ThreadedGenerateData() in each thread. 4) Call AfterThreadedGenerateData() Note that this flow of control is only available if a filter provides a ThreadedGenerateData() method and NOT a GenerateData() method.

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.

void itk::SLICImageFilter< TInputImage, TOutputImage, TDistancePixel >::GenerateData ( )
overrideprotectedvirtual

A version of GenerateData() specific for image processing filters. This implementation will split the processing across multiple threads. The buffer is allocated by this method. Then the BeforeThreadedGenerateData() method is called (if provided). Then, a series of threads are spawned each calling DynamicThreadedGenerateData(). After all the threads have completed processing, the AfterThreadedGenerateData() method is called (if provided). If an image processing filter cannot be threaded, the filter should provide an implementation of GenerateData(). That implementation is responsible for allocating the output buffer. If a filter can be threaded, it should NOT provide a GenerateData() method but should provide a DynamicThreadedGenerateData() instead.

template<typename TInputImage , typename TOutputImage , typename TDistancePixel = float>
virtual double itk::SLICImageFilter< TInputImage, TOutputImage, TDistancePixel >::GetAverageResidual ( ) const
virtual

Get the current average cluster residual.

After each iteration the residual is computed as the distance between the current clusters and the previous. This is averaged so that the value is independent of the number of clusters.

Methods invoked by Print() to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Post processing step to enforce superpixel morphology.

Enable an additional computation which ensures all label pixels of the same value are spatially connected. Disconnected labeled components are assigned a new value if of sufficient size, or are relabeled to the previously encountered value if small.

template<typename TInputImage , typename TOutputImage , typename TDistancePixel = float>
virtual void itk::SLICImageFilter< TInputImage, TOutputImage, TDistancePixel >::SetInitializationPerturbation ( bool  _arg)
virtual

Enable perturbation of initial cluster center location.

After grid based initialization, this option enables moving the initial cluster center location to the minimum gradient in a small neighborhood. If the grid size is less than three this is automatically disabled.

template<typename TInputImage , typename TOutputImage , typename TDistancePixel = float>
virtual void itk::SLICImageFilter< TInputImage, TOutputImage, TDistancePixel >::SetMaximumNumberOfIterations ( unsigned int  _arg)
virtual

Number of iterations to run.

Specify the number of iterations to run when optimizing the clusters.

template<typename TInputImage , typename TOutputImage , typename TDistancePixel = float>
virtual void itk::SLICImageFilter< TInputImage, TOutputImage, TDistancePixel >::SetSpatialProximityWeight ( double  _arg)
virtual

The spatial weight for the distance function.

Increasing this value makes the superpixel shape more regular, but more varied in image values. The range of the pixel values and image dimension can effect the appropriate value.

template<typename TInputImage , typename TOutputImage , typename TDistancePixel = float>
virtual void itk::SLICImageFilter< TInputImage, TOutputImage, TDistancePixel >::SetSuperGridSize ( SuperGridSizeType  _arg)
virtual

The expected superpixel size and shape.

The requested size of a superpixel used to form a regular grid for initialization and limits the search space for pixels. The size may be set anisotropically to provide a directional bias. This may be set to reflect spacing of this image.
