Detailed Description

template<typename TInputImage>
class rtk::TotalVariationImageFilter< TInputImage >

Compute the total variation of an Image.

TotalVariationImageFilter computes the total variation, defined as the L1 norm of the image of the L2 norm of the gradient, 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 pipeline with other filters and the total variation will only be recomputed if a downstream filter changes.

The filter passes its input through unmodified. The filter is threaded.
