Detailed Description

Class to extract a standard deviation image (or sdImage) based on the a neighbourhood.

By sdImage, we do not mean the standard deviation of the image, we mean that each pixel intensity in the sdImage is the standard deviation of the intensity value of a certain neighbourhood of the corresponding pixel in the original image. The 'variance image' is also simultaneously evaluated. The sdImage is extracted onto a different memory space and can be accessed using the getResult member function.

Constructor & Destructor Documentation

iptk::SdImage::SdImage (  void   )

Default constructor. Does nothing. Objects initialised by default construction should register the image by a call to setImage. This image is un-affected by any of the processes performed by the object.

iptk::SdImage::SdImage (  const iptk::Image &  im  )

Image registering constructor. Objects created using this constructor do not need to register an image separtely.

iptk::SdImage::SdImage (  const SdImage &  si  )

Copy constructor. This is only a reference copier. The new object and the old object share the same data space (and hence the data) in memory.

virtual iptk::SdImage::~SdImage (   )  [virtual]

Destructor. This destructor does nothing. The design of the class calls for nothing to be done.

Member Function Documentation

virtual iptk::Image iptk::SdImage::getVarianceImage (  void   )  [virtual]

Returns the variance image. The returned image is meaningfull only after a call to the process member function.

virtual void iptk::SdImage::process (  void   )  [virtual]

The function which actually extracts the sdImage. Set the neighbourhood size by a call to the setParams function before a call to this function. Else a default value of 3 will be used for the neighbourhood size. Implements iptk::NeighbourhoodStatisticsFilter.
