Constructor Details

GaussianScaleSpace

public GaussianScaleSpace(FloatProcessor fp,
 int P,
 int Q,
 double sigma_s,
 double sigma_0,
 int botLevel,
 int topLevel)

Constructor, builds a GaussianScaleSpace from a FloatProcessor.

Parameters:

fp - a FloatProcessor

P - the number of scale space octaves

Q - the number of scale steps (levels) per octave

sigma_s - the assumed sampling scale (typ. 0.5)

sigma_0 - the base scale of level 0

botLevel - the index of the bottom level in each octave

topLevel - the index of the to level in each octave
