## ◆ applyWindowFunction()

void vigra::applyWindowFunction | ( |  | ... | ) |

Apply a window function to each pixels of a given image.

This function calculates the results for a window function (given as a functor) when applied to the complete image. Also allows a correct border handling! See medianFilter() for an example of a quite basic window function and its application.If you pass a functor to this function, which implements the two functions:

1. Diff2D windowShape() const
   to return the filter window size, which has to be odd in each dimension and
2. void operator()(SrcIterator s, SrcAccessor s_acc, DestIterator d, DestAccessor d_acc)
   to compute the results of the current window,

this function calculates the results for the complete image.

All border treatment modes (except BORDER_TREATMENT_CLIP) are supported.

The input pixel type `T1` must be a linear space over the window functions' value_type `T`, i.e. addition of source values, multiplication with functions' values, and NumericTraits must be defined. The filters' value_type must be an algebraic field, i.e. the arithmetic operations (+, -, *, /) and NumericTraits must be defined.

Declarations:

pass 2D array views:

namespace vigra {
template <class T1, class S1,
class T2, class S2,
class ProcessingFunctor>
void
applyWindowFunction(MultiArrayView<2, T1, S1> const & src,

Usage:

#include <vigra/applywindowfunction.hxx>
Namespace: vigra

unsigned int w=1000, h=1000;
MultiArray<2, float> src(w,h), dest(w,h);

## ◆ doxygen_overloaded_function()

vigra::doxygen_overloaded_function | ( | template<... > void | separableConvolveBlockwise | ) |

Separated convolution on ChunkedArrays.

Declarations:

namespace vigra {
// apply each kernel from the sequence 'kernels' in turn
template <unsigned int N, class T1, class T2, class KernelIterator>
void separableConvolveBlockwise(const ChunkedArra<N, T1>& source, ChunkedArray<N, T2>& destination, KernelIterator kernels);

This function can be used to show a segmentation or node features of RAG on pixel / voxel level

## ◆ medianFilter()

void vigra::medianFilter | ( |  | ... | ) |

This function calculates the median of a window of given size for the complete image.

This function calculates the median of a window of given size for the complete image. It also allows a correct border handling, since it uses the applyWindowFunction environment for computation!All border treatment modes (except BORDER_TREATMENT_CLIP) are supported.

The input pixel type `T1` must be a linear space over the window functions' value_type `T`. Especially, the values must be sortable by std::sort, to derive the mean values aka the median.

pass 2D array views:

namespace vigra {
template <class T1, class S1,
class T2, class S2>
void

MultiArray<2, float> src(w,h), dest(w,h);
...
// apply a median filter with a window size of 5x5

This function calculates discrete upwinding scheme proposed by J. Weickert (2002) in Coherence-Enhancing Show Filters.

This function calculates of the coherence enhancing shock filter proposed by J. Weickert (2002) in Coherence-Enhancing Show Filters.

This function calculates of the coherence enhancing shock filter proposed by J. Weickert (2002): Coherence-Enhancing Show Filters. It uses the structure tensor information of an image and an iterative discrete upwinding scheme instead of pure dilation and erosion to perform the necessary morphological operations on the image.An image is upwinded positively (dilation), if the given second src is positive. Otherwise it is upwinds negatively (eroded). The effect can be steered by an upwinding factor.
