#include <itkComputeImageExtremaFilter.h>

Detailed Description

template<typename TInputImage>
class itk::ComputeImageExtremaFilter< TInputImage >

Compute min. max, variance and mean of an Image.

StatisticsImageFilter computes the minimum, maximum, sum, mean, variance sigma of an image. The filter needs all of its input image. It behaves as a filter with an input and output. Thus it can be inserted in a pipline with other filters and the statistics will only be recomputed if a downstream filter changes.

The filter passes its input through unmodified. The filter is threaded. It computes statistics in each thread then combines them in its AfterThreadedGenerate method.
