Given a label map and an optional intensity image, compute geometric features.
This filter enables the measurement of geometric features of all objects in a labeled ND volume. This labeled volume can represent, for instance, a medical image segmented into different anatomical structures or a microscope image segmented into individual cells. This filter is closely related to the itkLabelStatisticsImageFilter, which measures statistics of image regions defined by a labeled mask such as min, max, and mean intensity, intensity standard deviation, and bounding boxes. This filter, however, measures the geometry of the labeled regions themselves.
It calculates features similar to the regionprops command of Matlab. The set of measurements that it enables include: volume, centroid, eigenvalues, eigenvectors, axes lenghts, eccentricity, elongation, orientation, bounding box, oriented bounding box, and rotation matrix. These features are based solely on the labeled mask itself. It also calculates integrated intensity and weighted centroid, which are measured on an intensity image under the labeled mask. These features represent the set of currently calculated features, but the framework of the filter is designed so that it can be easily expanded to measure a wide variety of other features.

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 ThreadedGenerateData(). 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 an be threaded, it should NOT provide a GenerateData() method but should provide a ThreadedGenerateData() instead.

PushBackInput(), PushFronInput() in the public section force the input to be the type expected by an ImageToImageFilter. However, these methods end of "hiding" the versions from the superclass (ProcessObject) whose arguments are DataObjects. Here, we re-expose the versions from ProcessObject to avoid warnings about hiding methods from the superclass.
