Member Function Documentation

BuildPyramid() [1/2]

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

pure virtual

Builds a pyramid without copying the base level

Implemented in Freestyle::GaussianPyramid.

References l, Freestyle::x, and y.

getLevel()

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

virtual

Definition at line 52 of file ImagePyramid.cpp.

References _levels, and l.

getNumberOfLevels()

int Freestyle::ImagePyramid::getNumberOfLevels ( ) const

inline

Returns the number of levels in the pyramid

Definition at line 59 of file ImagePyramid.h.

Referenced by Freestyle::Canvas::loadMap().

height()

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

virtual

Returns the height of the level-th level image

Definition at line 113 of file ImagePyramid.cpp.

References _levels.

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
y	the ordinate specified in the finest level coordinate system
level	the level from which we want the pixel to be evaluated
