Member Function Documentation

BuildPyramid() [1/2]

virtual void Freestyle::ImagePyramid::BuildPyramid ( const GrayImage &  level0, unsigned  nbLevels  )

pure virtual

Builds the pyramid. must be overloaded by inherited classes. if nbLevels==0, the complete pyramid is built

Implemented in Freestyle::GaussianPyramid.

BuildPyramid() [2/2]

virtual void Freestyle::ImagePyramid::BuildPyramid ( GrayImage *  level0, unsigned  nbLevels  )

pure virtual

Builds a pyramid without copying the base level

Implemented in Freestyle::GaussianPyramid.

getLevel()

GrayImage * Freestyle::ImagePyramid::getLevel ( int  l )

virtual

Definition at line 60 of file ImagePyramid.cpp.

References l.

getNumberOfLevels()

int Freestyle::ImagePyramid::getNumberOfLevels ( ) const

inline

Returns the number of levels in the pyramid

height()

int Freestyle::ImagePyramid::height ( int  level = 0 )

virtual

Returns the height of the level-th level image

pixel()

float Freestyle::ImagePyramid::pixel ( int  x, int  y, int  level = 0  )

virtual

Returns the pixel x,y using bilinear interpolation.

Parameters

x	the abscissa specified in the finest level coordinate system
